NOTE 1: - GENERAL	12 Months Ended

Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1:– GENERAL a. Corporate structure: Arotech Corporation (“Arotech”) and its wholly-owned subsidiaries (the “Company”) provide defense and security products for the military, law enforcement, emergency services and homeland security markets, including zinc-air and lithium batteries and chargers, and multimedia interactive simulators/trainers. The Company operates primarily through its wholly-owned subsidiaries FAAC Incorporated, a Michigan corporation located in Ann Arbor, Michigan (Training and Simulation Division) with a location in Orlando, Florida; Epsilor-Electric Fuel Ltd. (“Epsilor-EFL”), an Israeli corporation located in Beit Shemesh, Israel (between Jerusalem and Tel-Aviv), Dimona, Israel (in Israel’s Negev desert area) and Sderot, Israel (near the Gaza Strip) (Power Systems Division); UEC Electronics, LLC (“UEC”), a South Carolina limited liability company located in Hanahan, South Carolina (Power Systems Division). b. Discontinued operations Asset Held for Sale and Discontinued Operations In August 2016, the Board approved a strategic shift to discontinue the Flow Battery segment (“the segment”) with an effective date of August 31, 2016. The principal activities of the Flow Battery segment were research and development related and were focused on developing a commercial application based upon the Iron Flow Storage concept. The assets of the Flow Battery segment of $270,139 were classified as held for sale as of December 31, 2016. During the fourth quarter of 2017, it was determined that the Company was not able to execute its plan to sell the assets associated with the Flow Battery segment. As a result, assets in the amount of $270,000 have been reclassified on the consolidated balance sheet into property and equipment, which are being used in operations and therefore not considered to be impaired as of December 31, 2017. The amounts presented in the consolidated statements of comprehensive income as discontinued operations represented research and development and general and administrative expenses. As the Flow Battery segment was reported within the Epsilor-EFL legal entity and the legal entity has net operating loss carryforwards for which the Company has recorded a valuation allowance, there was no tax impact. Included in the Flow Battery segment’s general and administrative expenses for the year ended December 31, 2016, was a contractual buyout associated with the termination of the former Chairman of the Flow Battery segment of $524,052. The impact of the discontinued operations on operating and investing activities within the consolidated statements of cash flows for the year ended December 31, 2016, and 2015 was ($1,337,751) and ($879,428); and ($252,064) and ($22,075), respectively. Unless otherwise indicated, discontinued operations are not included in the reported results. The Notes to the Consolidated Financial Statements relate to the Company’s continuing operations. c. Related parties Note Receivable Two former executives entered into non-recourse promissory notes whereby the Company provided the note to the executives and the executives in turn exercised stock options. The promissory notes originally accrued interest at an annual rate of 1% over the then federal funds rate. In 2008, the Company stopped accruing interest on the promissory notes. As of December 31, 2017 and 2016, the aggregate amount outstanding pursuant to this promissory note was $908,054. UEC Facility Headquarters On October 31, 2014, the Company entered into a lease agreement with UEC Properties, LLC, a company controlled by the former owners of UEC, and now consultants and shareholders of the Company, for land and buildings that represent the headquarters of UEC Electronics. The lease term with UEC Properties commenced on January 1, 2015 and it extends for ten years, expiring on December 31, 2024. The 2017 monthly lease payment is $30,325 and increases at a rate of 2.5% per year through the term of the lease. Lease expense recognized in 2017 and 2016 was $364,000 and $355,000, respectively. Upon written notice, the Company and UEC Properties, LLC, may elect to terminate the lease after five years. Admiralty Partners On February 2, 2016, the Company and Admiralty Partners (the “Investor”) entered into a Stock Purchase Agreement (the “Investment Agreement”) providing for the sale to the Investor of a total of 1,500,000 shares of the Company’s common stock at a price valued at $1.99 per share. As the Investor was also given the right to nominate a member of the Board of Directors pursuant to the terms of the Investment Agreement, and the shares were issued as a discount to the then market price, this resulted in additional stock compensation expense of $375,000. Subsequently, on February 3, 2016, the Company entered into a consulting agreement with the Investor for a period of three years. In exchange, the Company pays an annual fee equal to the difference between total accrued compensation of the Board member and $125,000. The agreement can be terminated by either party upon sufficient written notice. Total compensation expense recognized in 2017 and 2016 was $49,000 and $27,000, respectively.

NOTE 2: - SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE 2:– SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). a. Principles of consolidation: The consolidated financial statements include the accounts of Arotech and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. b. Financial Statements in U.S. Dollars: A majority of the revenues of the Company are generated in U.S. dollars (“dollars”). In addition, a substantial portion of the Company’s costs are incurred in dollars. Management believes that the dollar is the primary currency of the economic environment in which the Company operates. Thus, the functional and reporting currency of the Company including most of its subsidiaries is the dollar. Accordingly, monetary accounts maintained in currencies other than dollars are re-measured into dollars, with resulting gains and losses reflected in the consolidated statements of operations and comprehensive income as financial income or expenses, as appropriate. The majority of transactions of Epsilor-EFL are in New Israel Shekels (“NIS”) and a substantial portion of Epsilor-EFL’s costs is incurred in NIS. Management believes that the NIS is the functional currency of Epsilor-EFL. Accordingly, the financial statements of Epsilor-EFL have been translated into dollars. All balance sheet accounts have been translated using the exchange rates in effect at the balance sheet date. Statement of operations, cash flows, and comprehensive income amounts have been translated using the weighted average exchange rate for the period. The resulting translation adjustments are reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity. c. Cash equivalents: Cash equivalents are short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less when acquired. d. Restricted collateral deposits: Restricted collateral deposits are primarily invested in highly liquid deposits which are used as security for the Company’s performance guarantees at FAAC and Epsilor-EFL. e. Inventories: Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at lower of cost or net realizable value and expense estimates are made for excess and obsolete inventories. Based on this evaluation, provisions are made to write inventory down to its market value. In 2017, 2016, and 2015, the Company wrote off approximately $407,000, $359,000, and $321,000, respectively, of obsolete inventory, which has been included in the cost of revenues. Cost is determined by first-in, first-out (“FIFO”) method. f. Property and equipment: Depreciation is calculated by the straight-line method over the following estimated useful lives of the assets: Depreciable life (in years) Computers and related equipment 3 to 5 Motor vehicles 5 to 7 Office furniture and equipment 3 to 5 Machinery, equipment and installations 5 to 10 Buildings 30 Land Not depreciated Leasehold improvements Shorter of the term of the lease or the life of the asset Demo inventory 3 to 5 The Company tests long-lived asset groups for recoverability when changes in circumstances indicate the carrying value may not be recoverable, for example, when there are material adverse changes in projected revenues or expenses, significant underperformance relative to historical or projected operating results, or significant negative industry or economic trends. The Company also performs a test for recoverability when management has committed to a plan to sell or otherwise dispose of an asset group. The Company evaluates recoverability of an asset group by comparing its carrying value to the future net undiscounted cash flows that the Company expects will be generated by the asset group. If the comparison indicates that the carrying value of an asset group is not recoverable, the Company recognizes an impairment loss for the excess of carrying value over the estimated fair value. When the Company recognizes an impairment loss for assets to be held and used, the Company depreciates the adjusted carrying amount of those assets over their remaining useful life. No impairment losses were recognized for the year ended December 31, 2017. g. Goodwill and Other Intangible Assets: Certain business acquisitions have resulted in the recording of goodwill and indefinite-life intangible assets, primarily trademark assets, which are not amortized. Goodwill is tested for impairment at the reporting unit level, which is the operating segment or one level below the operating segment, also known as a component. Two or more components of an operating segment shall be aggregated into a single reporting unit if the components have similar economic characteristics, based on an assessment of various factors. The Company has determined that the Training and Simulation Division and the Power System Division segments are separate reporting units. The Company performs its annual impairment assessment for goodwill and other indefinite-life intangible assets as of December 31 or more frequently if events or changes in circumstances indicate that the asset might be impaired. When testing goodwill for impairment, the Company may conduct a qualitative assessment by analyzing a variety of factors that could influence the fair value of the reporting unit or indefinite-life intangible, including, but not limited to: the results of prior quantitative assessments performed; changes in the carrying amount of the reporting unit or indefinite-life intangible; actual and projected revenue and operating margin; relevant market data for both the Company and its peer companies; industry outlooks; macroeconomic conditions; liquidity; changes in key personnel; and the Company’s competitive position. The Company uses significant judgment to evaluate the totality of these events and factors to make the determination of whether it is more likely than not that the fair value of the reporting unit or indefinite-life intangible is less than its carrying value. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, it then performs the impairment evaluation using a quantitative assessment. Under the quantitative assessment, the first step identifies whether there is a potential impairment by comparing the fair value of a reporting unit to the carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds the fair value, then a test is performed to determine the implied fair value of goodwill. An impairment loss is recognized based on the amount that the carrying amount of goodwill exceeds the implied fair value. When measuring the fair value of its reporting units in the quantitative assessment, the Company uses widely accepted valuation techniques, applying a combination of the income approach (discounted cash flows) and market approach (market multiples). When preparing discounted cash flow models under the income approach, the Company uses internal forecasts to estimate future cash flows expected to be generated by the reporting units. To discount these cash flows, the Company uses the expected cost of equity, determined by using a capital asset pricing model. The Company believes the discount rates used appropriately reflect the risks and uncertainties in the financial markets generally and specifically in the Company’s internally-developed forecasts. When using market multiples under the market approach, the Company applies comparable publicly traded companies’ multiples ( e.g. h. Revenue recognition: The Company is a defense and security products and services company, engaged in two business areas: interactive simulation for military, law enforcement and commercial markets; and power systems and batteries for the military, commercial and medical markets. During 2017, 2016, and 2015, the Company recognized revenues (i) from the sale and customization of interactive training systems and from the maintenance services in connection with such systems (Training and Simulation Division); (ii) from the sale of batteries, chargers and adapters, and under certain development contracts; and (iii) from the sale of lifejacket lights (Power Systems Division). Revenues from certain products sold by the Power Systems Division are recognized when persuasive evidence of an agreement exists, delivery has occurred, the fee is fixed or determinable, collectability is probable, and no further obligation remains. Typically revenue is recognized, per the contract, when the transaction is entered into the U.S. Government’s Wide Area Workflow system, which occurs after the products have been accepted at the plant or when shipped. Sales to other entities are recorded in accordance with the contract, either when shipped or delivered. Normally there are no further obligations that would preclude the recognition of revenue. Additionally, certain contracts are recognized using contract accounting on a percentage of completion method. Revenues from contracts in the Training and Simulation Division and Power Systems Division that involve customization of the system to customer specifications are recognized using contract accounting on a percentage of completion method, in accordance with the “Input Method.” The amount of revenue recognized is based on the percentage to completion achieved. The percentage to completion is measured by monitoring progress using records of actual time, materials and other costs incurred to date in the project compared to the total estimated project requirement. Estimates of total project requirements are based on prior experience of customization, delivery and acceptance of the same or similar technology and are reviewed and updated regularly by management. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are first determined, in the amount of the estimated loss on the entire contract. Normally there are no further obligations that would preclude the recognition of revenue. The Company believes that the use of the percentage of completion method is appropriate for certain contracts as the Company has the ability to make reasonably dependable estimates of the extent of progress towards completion, contract revenues and contract costs. In addition, contracts executed include provisions that clearly specify the enforceable rights regarding services to be provided and received by the parties to the contracts, the consideration to be exchanged and the manner and the terms of settlement, including in cases of terminations for convenience. In all cases, the Company expects to perform its contractual obligations and its customers are expected to satisfy their obligations under the contract. Revenues from products that do not require significant customization are recognized when persuasive evidence of an agreement exists, delivery has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable. Maintenance and support revenue included in multiple element arrangements is deferred and recognized on a straight-line basis over the term of the maintenance and support services. Revenues from training are recognized when it is performed. The Vendor Specific Objective Evidence (“VSOE”) of fair value of the maintenance, training and support services is determined based on the price charged when sold separately or when renewed. i. Trade receivables The Company records trade accounts receivable at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on the trade accounts receivable balances and charged to the provision for doubtful accounts. The Company calculates this allowance based on its history of write-offs, the level of past-due accounts based on the contractual terms of the receivables, and its relationships with, and the economic status of, its customers. During the years ended December 31, 2017 and 2016, the Company made no provisions or had any recoveries of doubtful accounts and had no reserves at either year end. The Company believes its exposure to concentrations of credit risk is limited due to the nature of its operations. Unbilled receivables include cost and gross profit earned in excess of billing. Deferred revenues include unearned amounts received under maintenance and support services, customer prepayments and billing in excess of costs and estimated earnings on uncompleted contracts. j. Warranty: The Company typically offers a one to two year warranty for many of its products. The specific terms and conditions of those warranties vary depending upon the product sold and country in which the Company does business. The Company estimates the costs that may be incurred under its basic limited warranty, including parts and labor, and records deferred revenue in the amount of such costs at the time product revenue is recognized in the Training and Simulation Division. In the Power Systems Division, warranty costs are estimated, accrued and recorded on the balance sheet in deferred revenues. Factors that affect the Company’s warranty liability include the number of installed units, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its reserves and adjusts the amounts as necessary. (See Note 16.) k. Research and development cost: The Company capitalizes certain software development costs, subsequent to the establishment of technological feasibility. Based on the Company’s product development process, technological feasibility is established upon the completion of a working model or a detailed program design. Research and development costs incurred in the process of developing product improvements or new products are generally charged to expenses as incurred. Significant costs incurred by the Company between completion of the working model or a detailed program design and the point at which the product is ready for general release have been capitalized. Capitalized software costs will be amortized by the greater of the amount computed using: (i) the ratio that current gross revenues from sales of the software bears to the total of current and anticipated future gross revenues from sales of that software, or (ii) the straight-line method over the estimated useful life of the product (one to three years). The Company assesses the net realizable value of this intangible asset on a regular basis by determining whether the amortization of the asset over its remaining life can be recovered through undiscounted future operating cash flows from the specific software product sold. Based on its most recent analyses, management believes that no impairment of capitalized software development costs exists as of December 31, 2017. In 2017 and 2016, the Training and Simulation Division capitalized approximately $588,000 and $364,000, respectively, in software development costs that will be amortized on a straight-line method over 2 years, the useful life of the software. l. Income taxes: The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liability account balances are determined based on tax credit carryforwards and differences between the financial reporting and the tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value. Accounting standards prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. The Company must determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. Uncertain tax positions require determinations and estimated liabilities to be made based on provisions of the tax law which may be subject to change or varying interpretation. If the Company’s determinations and estimates prove to be inaccurate, the resulting adjustments could be material to the Company’s future financial statements. See Income Tax Footnote to the Consolidated Financial Statements for more information regarding income taxes (Note 13). m. Concentrations of credit risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted collateral deposits and trade receivables. Cash and cash equivalents are invested mainly in U.S. dollar deposits with major Israeli and U.S. banks. Such deposits in the U.S. may be in excess of insured limits and are not insured in other jurisdictions. Management believes that the financial institutions that hold the Company’s investments are financially sound and, accordingly, minimal credit risk exists with respect to these investments. The trade receivables of the Company are mainly derived from sales to customers located primarily in the United States and Israel along with the countries listed in footnote 15.c. Management believes that credit risks are moderated by the diversity of its end customers and geographical sales areas. The Company performs ongoing credit evaluations of its customers’ financial condition. The Company had no off-balance-sheet concentration of credit risk such as foreign exchange contracts, option contracts or other foreign currency hedging arrangements as of December 31, 2017 and 2016. n. Basic and diluted net income per share: Basic net income per share is computed based on the weighted average number of shares of common stock and participating securities outstanding during each year. Diluted net income per share includes the dilutive effect of additional potential common stock issuable under its share-based compensation plans, using the “treasury stock” method. Unvested restricted stock issued to its employees and directors are “participating securities” and as such, are included, net of estimated forfeitures, in the total shares used to calculate the Company’s basic and diluted net income per share. In the event of a net loss, unvested restricted stock awards are excluded from the calculation of both basic and diluted net loss per share. The total weighted average number of shares related to the outstanding common stock equivalents excluded from the calculations of diluted net income per share were none, none, and 602,740 for the years ended December 31, 2017, 2016, and 2015, respectively. o. Accounting for stock-based compensation: Stock-based awards to employees are recognized as compensation expense based on the calculated fair value on the date of grant. The costs are amortized over the straight line vesting period. The Company granted restricted stock and restricted stock units in 2017, 2016, and 2015. The Company typically uses a 5-10% forfeiture rate for restricted stock and restricted stock units and adjusts both forfeiture rates based on historical forfeitures. Each restricted stock unit is equal to one share of Company stock and is redeemable only for stock. p. Fair value of financial instruments: The following methods and assumptions were used by the Company in estimating their fair value disclosures for financial instruments using the required three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which may require the Company to develop its own assumptions. The carrying amounts of cash and cash equivalents, restricted collateral deposits, trade and other receivables, short-term bank credit, and trade payables approximate their fair value due to the short-term maturity of such instruments (Level 1). The fair values of long-term promissory notes are estimated by discounting the future cash flows using current interest rates for loans of similar terms and maturities. The carrying amount of the long-term debt and contractual severance approximates the estimated fair values at December 31, 2017, based upon the Company’s ability to acquire similar debt or fulfill similar obligations at similar maturities (Level 3). q. Severance pay: The Company’s liability for severance pay for its Israeli employees is calculated pursuant to Israeli severance pay law based on the most recent salary of the employees multiplied by the number of years of employment as of the balance sheet date. Israeli employees are entitled to one month’s salary for each year of employment, or a portion thereof. The Company’s liability for all of its Israeli employees is fully provided for by monthly deposits into severance pay funds held by insurance companies on behalf of the employees, insurance policies and by accrual. The fair value of these funds, which are considered Level 2 fair value measurements, is recorded as an asset in the Company’s consolidated balance sheet. In addition, according to certain employment agreements, the Company is obligated to provide for a special severance pay in addition to amounts due to certain employees pursuant to Israeli severance pay law. During the years ended December 31, 2017, 2016, and 2015, the Company had made provisions of $106,000, $1,022,000, and $143,000, respectively, for this special severance pay. As of December 31, 2017 and 2016 the unfunded severance pay amounted to $142,000 and $2,130,000, respectively. Severance expenses from continuing operations for the years ended December 31, 2017, 2016, and 2015, amounted to $728,000, $1,389,000, and $625,000, respectively. In December 2016, the Company and its former Chief Executive Officer (“former Executive”) signed an agreement whereby the Company and the former Executive agreed to early termination of the former Executive’s employment agreement. The additional expense and accrual, included above, related to this termination, were approximately $925,000 and $2,050,000, respectively. r. Advertising costs: The Company records advertising costs as incurred. Advertising expense for the years ended December 31, 2017, 2016, and 2015 was approximately $94,000, $72,000, and $159,000, respectively. s. New accounting pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as a new Topic, Accounting Standards Codification (“ASC”) 606. The new revenue recognition standard relates to revenue from contracts with customers, which, along with amendments issued in 2015 and 2016, will supersede nearly all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The underlying principle is to use a five-step analysis of transactions to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Additionally, the new standard requires enhanced disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including revenue recognition policies to identify performance obligations, assets recognized from costs incurred to obtain and fulfill a contract, and significant judgments in measurement and recognition. The Company’s task force has reviewed significant contracts with customers and the promised goods and/or services associated with the revenue streams for each segment. The Company has evaluated the distinct performance obligations and the pattern of revenue recognition of these significant contracts in advance of the implementation of the standard. In our review of contracts in each revenue stream, the Company noted no material impact in the implementation of the standard. The Company has determined the impact of adopting the standard on its control framework and notes minimal, insignificant changes to its system and other controls process. The standard, as amended, will be effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted the standard on a modified retrospective basis on January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Upon adoption, the Company expects that the ROU asset and lease liability will be recognized in the balance sheets in amounts that will be material. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new standard introduces targeted amendments intended to simplify the accounting for stock compensation. Among other things, the ASU requires all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement. The amendments are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this new standard was not material to the consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15 (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments provide guidance on eight specific cash flow issues for which the current accounting framework does not provide specific guidance. The amendments are effective for annual periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company finalized its analysis and the adoption of this guidance will not have a material impact on its consolidated financial statements and its internal controls over financial reporting. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test and requires businesses to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendments are effective for annual periods beginning after December 15, 2019 with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of its pending adoption of the new standard on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments are effective for annual periods beginning after December 15, 2017 with a limited scope of early adoption. The adoption of this new standard did not impact the Company and will apply for any future acquisitions. In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). The accounting standard allows for the optional reclassification of stranded tax effects within accumulated other comprehensive income to retained earnings that arise due to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The amount of the reclassification would reflect the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of enactment of the Tax Act and other income tax effects of the Tax Act on items remaining in accumulated other comprehensive income. The standard, will be effective for annual periods beginning after December 15, 2018, including interim periods within that reporting period with early adoption permitted. The Company is currently evaluating the impact of its pending adoption of the new standard on its consolidated financial statements. u. Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. v. Reclassification: Prior period amounts are reclassified, when necessary, to conform to the current period presentation. w. Business Combinations: The Company recognizes the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. The Company assesses the fair value of assets, including intangible assets, using a variety of methods and each asset is measured at fair value from the perspective of a market participant. The method used to estimate the fair values of intangible assets incorporates significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant’s use of the asset and the appropriate discount rates for a market participant. Assets recorded from the perspective of a market participant that are determined to not have economic use for us are expensed immediately. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	NOTE 7:– GOODWILL AND OTHER INTANGIBLE ASSETS, NET a. Goodwill Goodwill and indefinite lived assets are assessed annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. For the years ended December 31, 2017 and 2016, respectively, the Company performed a qualitative assessment for its Training and Simulation reporting unit and the Company determined that it was more likely than not that the fair values of its reporting unit exceeded its carrying value. For its Power Systems reporting unit, the Company determined that it was necessary to perform a quantitative assessment of goodwill for the purpose of determining whether an impairment existed at December 31, 2017. When conducting this analysis, the Company engaged third party valuation experts with a detailed understanding of its Power Systems reporting unit to perform a valuation of the Power Systems reporting unit on a going concern basis. The Company prepared a discounted cash flow analysis over a five year period so as to derive a reasonable view of the cash flows that the Power Systems reporting unit are projected to generate from 2018-2022. As a result of its quantitative analysis, in which the Company computed the fair value of the Power Systems reporting unit, the Company concluded that the fair value of the reporting unit exceeded the reporting unit’s carrying value by approximately 22%. The Company also considered its current market capitalization compared to the sum of the estimated fair values of its reporting units in conjunction with each impairment assessment. As of the December 31, 2017 valuation date, its market capitalization was approximately $92.1 million, which did not, in management’s view, suggest that the fair value estimates used in its impairment assessment required any adjustment. As a result of these analyses, the Company concluded that the goodwill recorded in relation to the Power Systems reporting unit was not impaired at December 31, 2017. A summary of the goodwill by business segment is as follows: December 31, 2016 Additions Adjustments (currency) December 31, 2017 Training and Simulation Division $ 24,435,641 $ – $ – $ 24,435,641 Power Systems Division 21,053,876 – 648,519 21,702,395 Total $ 45,489,517 $ – $ 648,519 $ 46,138,036 b.

Disclosure Text Block [Abstract]
Short-term Debt [Text Block]	NOTE 8:– LOANS The Company maintains credit facilities with JPMorgan Chase Bank, N.A. (“Chase”), whereby Chase provides (i) a $15,000,000 revolving credit facility (“Revolver”), (ii) a $10,000,000 Term Loan (“Term Loan A”), (iii) a $1,730,895 Mortgage Loan (“Term Loan B”) and (iv) a $1,358,000 Mortgage Loan (“Term Loan C”); collectively referred to as the “Credit Facilities.” The maturity of the Revolver is March 11, 2021. The Revolver maintains an interest rate on a scale ranging from LIBOR plus 1.75% up to LIBOR plus 3.00%. The effective interest rate for the revolver at December 31, 2017 was 5.0%. The balance at December 31, 2017 and December 31, 2016 was $5.1 million and $3.0 million, respectively. The maturity of the Term Loan A is March 11, 2021. Term Loan A maintains an interest rate on a scale ranging from LIBOR plus 2.0% up to LIBOR plus 3.25%. The repayment of Term Loan A consists of 60 consecutive monthly payments of principal plus accrued interest based on annual principal reductions of 10% during the first year, 20% during the second through fourth years, and 30% during the fifth year. The effective interest rate for the Term Loan at December 31, 2017 was 5.25%. The balance at December 31, 2017 and December 31, 2016 was $7.7 million and $9.3 million, respectively. During the quarter ended June 30, 2017, the Company purchased land and a building, previously leased by its Training and Simulation Division, in Ann Arbor, Michigan. As a result, the Company now maintains two Mortgage Loans (“Term Loans B and C”). The maturities of Term Loans B and C are June 1, 2024 and maintain an interest rate on a scale identical to Term Loan A.

NOTE 13_ - INCOME TAXES

NOTE 13: - INCOME TAXES	12 Months Ended
	Dec. 31, 2017
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 13:– INCOME TAXES a. General: The U.S. Tax Cuts and Jobs Act (“Tax Act”) was enacted on December 22, 2017. The Tax Act makes broad complex changes to the U.S. tax code including, but not limited to, reduction of the U.S. federal corporate tax rate from 35% to 21%, requiring companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings and additional limitations on the deductibility of interest. The SEC issued Staff Accounting Bulletin No. 118 (SAB 118) in December, 2017, to provide guidance on accounting for the effects of the Tax Act. SAB 118 provides for a measurement period of up to one year from the Tax Act enactment date for companies to complete their assessment of and accounting for those effects of the Tax Act. Under SAB 118, a company must first reflect the income tax effects of the Tax Act for which the accounting is complete in the period of the date of enactment. To the extent the accounting for other income tax effects is incomplete, but a reasonable estimate can be determined, companies must record a provisional estimate to be included in their financial statements. For any income tax effect for which a reasonable estimate cannot be determined, an entity must continue to apply ASC 740 based on the provisions of the tax laws in effect immediately prior to the Tax Act being enacted until such time as a reasonable estimate can be determined. The Company has recorded a provisional deferred income tax benefit of $3.2 million in the period ended December 31, 2017 related to the change in corporate tax rate from 35% to 21% as a result of the Tax Act. The Company requires additional time to complete its analysis of the impacts of the Tax Act and therefore its accounting for the Tax Act is provisional but is a reasonable estimate based on available information. The Company will complete its analysis and finalize its accounting for this provisional estimate during the one-year measurement period as prescribed by SAB 118. For the year ended December 31, 2017, the Company was not required to record any provisional amounts for the Company’s foreign subsidiary relating to the one-time tax on accumulated foreign earnings provision of the Tax Act due to the accumulated net loss position of the foreign subsidiary. Beginning in 2018, the Tax Act provides a 100% deduction for dividends received from 10-percent owned foreign corporations by U.S. corporate shareholders, subject to a one-year holding period. Although dividend income is now exempt from U.S. federal tax in the hands of the U.S. corporate shareholders, companies must still apply the guidance of ASC 740-30-25-18 to account for the tax consequences of outside basis differences and other tax impacts of their investments in non-U.S. subsidiaries. The Tax Act limits net operating loss (“NOL”) deductions to 80 percent of taxable income for tax years beginning after December 31, 2017. The amendments disallow the carryback of NOLs but allow for the indefinite carryforward of NOLs, which would be considered an indefinite lived asset. As of December 31, 2017, the Company had net operating loss (“NOL”) carryforwards for U.S. federal income tax purposes of $40.7 million, which are available to offset future taxable income, if any, expiring in 2021 through 2037. Utilization of U.S. net operating losses is subject to substantial annual limitations due to the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses before utilization. At December 31, 2017, the Company had net deferred tax assets before valuation allowance of $37.5 million. The deferred tax assets are primarily composed of federal, state and foreign tax NOL carryforwards. Due to uncertainties surrounding the Company’s ability to generate future taxable income to realize these assets, a full valuation allowance has been established to offset its net deferred tax assets. Additionally, the future utilization of the Company’s NOL carryforwards to offset future taxable income is subject to a substantial annual limitation as a result of IRC Section 382 changes that have occurred. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance. The Company has indefinite-lived intangible assets consisting of trademarks and goodwill. These intangible assets are not amortized for financial reporting purposes. However, these assets are tax deductible, and therefore amortized over 15 years for tax purposes. As such, deferred income tax expense and a deferred tax liability arise as a result of the tax-deductibility of these assets. The resulting deferred tax liability, which is expected to continue to increase over time, will have an indefinite life, resulting in what is referred to as a “naked tax credit.” This deferred tax liability could remain on the Company’s balance sheet permanently unless there is an impairment of the related assets (for financial reporting purposes), or the business to which those assets relate were to be disposed of. Due to the fact that the aforementioned deferred tax liability could have an indefinite life, it is not netted against the Company’s deferred tax assets when determining the required valuation allowance. Doing so would result in the understatement of the valuation allowance and related deferred income tax expense. The Company has also evaluated its income tax positions under FASB ASC 740-10 as of December 31, 2017 and the Company believes that it has no material uncertain tax positions and therefore has no uncertain tax position reserves and does not expect to provide for any such reserves. The Company does not believe that the unrecognized tax benefits will change within 12 months of this reporting date. It is the Company’s policy that any assessed penalties and interest on uncertain tax positions would be charged to income tax expense. The Company files income tax returns, including returns for its subsidiaries, with federal, state, local and foreign jurisdictions. The Company files consolidated tax returns for its U.S. entities. b. Israeli subsidiary (Epsilor-EFL): Epsilor-EFL’s tax rate was 24% for 2017, 25% for 2016 and 26.5% for 2015. In addition, dividends paid from the profits of Epsilor-EFL are subject to tax at the rate of 15% in the hands of their recipient. Management has indicated that it has no intention of declaring a dividend. The Israeli government has established certain development zones so as to incentivize business development and export activities. Companies that reside in this zone and meet certain criteria are subject to a favorable tax rates. Epsilor-EFL is located in an approved development zone, however, currently does not meet the criteria established by the government to obtain the tax incentives. As of December 31, 2017, the Company has tax loss carryforwards, generated by the predecessor of Epsilor-EFL, of $91.5 million, which is available indefinitely to offset future taxable income. Due to the 2009 merger of EFL-Epsilor, the utilization of the tax loss carryforward is subject to annual limitations. c. Consolidated deferred income taxes: Deferred income taxes reflect tax credit carryforwards and the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. Significant components of the Company’s deferred tax assets are as follows: December 31, 2017 2016 U.S. operating loss carryforward $ 9,271,258 $ 16,869,205 Foreign operating loss carryforward 21,949,779 19,696,756 Total operating loss carryforward 31,221,037 36,565,961 Temporary differences: Compensation and benefits 1,530,669 2,417,056 Warranty reserves 871,219 1,263,499 Foreign temporary differences 684,230 1,112,113 Definite lived intangible assets 1,696,965 304,063 Fixed assets 968,053 1,458,138 AMT credit 387,068 387,068 All other temporary differences 524,781 (57,646 ) Total temporary differences 6,662,985 6,884,291 Deferred tax asset before valuation allowance 37,884,022 43,450,252 Valuation allowance (37,496,954 ) (43,063,184 ) Total deferred tax asset $ 387,068 $ 387,068 Deferred tax liability – intangible assets $ 5,987,789 $ 8,255,193 Net deferred tax liability – intangible assets $ 5,600,721 $ 7,868,125 The Company provided valuation allowances for the deferred tax assets resulting from tax loss carryforwards and other temporary differences. At present, management currently believes that it is more likely than not that the deferred tax assets related to the operating loss carryforwards and other temporary differences will not be realized. d. Income from continuing operations before taxes on income are as follows: Year ended December 31 2017 2016 2015 Domestic $ 476,327 $ (2,133,486 ) $ (3,071,694 ) Foreign 1,333,679 1,437,332 2,181,671 $ 1,810,006 $ (696,154 ) $ (890,023 ) e.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of consolidation: The consolidated financial statements include the accounts of Arotech and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Financial Statements in U.S. Dollars: A majority of the revenues of the Company are generated in U.S. dollars (“dollars”). In addition, a substantial portion of the Company’s costs are incurred in dollars. Management believes that the dollar is the primary currency of the economic environment in which the Company operates. Thus, the functional and reporting currency of the Company including most of its subsidiaries is the dollar. Accordingly, monetary accounts maintained in currencies other than dollars are re-measured into dollars, with resulting gains and losses reflected in the consolidated statements of operations and comprehensive income as financial income or expenses, as appropriate. The majority of transactions of Epsilor-EFL are in New Israel Shekels (“NIS”) and a substantial portion of Epsilor-EFL’s costs is incurred in NIS. Management believes that the NIS is the functional currency of Epsilor-EFL. Accordingly, the financial statements of Epsilor-EFL have been translated into dollars. All balance sheet accounts have been translated using the exchange rates in effect at the balance sheet date. Statement of operations, cash flows, and comprehensive income amounts have been translated using the weighted average exchange rate for the period. The resulting translation adjustments are reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash equivalents: Cash equivalents are short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less when acquired.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted collateral deposits: Restricted collateral deposits are primarily invested in highly liquid deposits which are used as security for the Company’s performance guarantees at FAAC and Epsilor-EFL.
Inventory, Policy [Policy Text Block]	Inventories: Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at lower of cost or net realizable value and expense estimates are made for excess and obsolete inventories. Based on this evaluation, provisions are made to write inventory down to its market value. In 2017, 2016, and 2015, the Company wrote off approximately $407,000, $359,000, and $321,000, respectively, of obsolete inventory, which has been included in the cost of revenues. Cost is determined by first-in, first-out (“FIFO”) method.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and equipment: Depreciation is calculated by the straight-line method over the following estimated useful lives of the assets: Depreciable life (in years) Computers and related equipment 3 to 5 Motor vehicles 5 to 7 Office furniture and equipment 3 to 5 Machinery, equipment and installations 5 to 10 Buildings 30 Land Not depreciated Leasehold improvements Shorter of the term of the lease or the life of the asset Demo inventory 3 to 5 The Company tests long-lived asset groups for recoverability when changes in circumstances indicate the carrying value may not be recoverable, for example, when there are material adverse changes in projected revenues or expenses, significant underperformance relative to historical or projected operating results, or significant negative industry or economic trends. The Company also performs a test for recoverability when management has committed to a plan to sell or otherwise dispose of an asset group. The Company evaluates recoverability of an asset group by comparing its carrying value to the future net undiscounted cash flows that the Company expects will be generated by the asset group. If the comparison indicates that the carrying value of an asset group is not recoverable, the Company recognizes an impairment loss for the excess of carrying value over the estimated fair value. When the Company recognizes an impairment loss for assets to be held and used, the Company depreciates the adjusted carrying amount of those assets over their remaining useful life. No impairment losses were recognized for the year ended December 31, 2017.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets: Certain business acquisitions have resulted in the recording of goodwill and indefinite-life intangible assets, primarily trademark assets, which are not amortized. Goodwill is tested for impairment at the reporting unit level, which is the operating segment or one level below the operating segment, also known as a component. Two or more components of an operating segment shall be aggregated into a single reporting unit if the components have similar economic characteristics, based on an assessment of various factors. The Company has determined that the Training and Simulation Division and the Power System Division segments are separate reporting units. The Company performs its annual impairment assessment for goodwill and other indefinite-life intangible assets as of December 31 or more frequently if events or changes in circumstances indicate that the asset might be impaired. When testing goodwill for impairment, the Company may conduct a qualitative assessment by analyzing a variety of factors that could influence the fair value of the reporting unit or indefinite-life intangible, including, but not limited to: the results of prior quantitative assessments performed; changes in the carrying amount of the reporting unit or indefinite-life intangible; actual and projected revenue and operating margin; relevant market data for both the Company and its peer companies; industry outlooks; macroeconomic conditions; liquidity; changes in key personnel; and the Company’s competitive position. The Company uses significant judgment to evaluate the totality of these events and factors to make the determination of whether it is more likely than not that the fair value of the reporting unit or indefinite-life intangible is less than its carrying value. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, it then performs the impairment evaluation using a quantitative assessment. Under the quantitative assessment, the first step identifies whether there is a potential impairment by comparing the fair value of a reporting unit to the carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds the fair value, then a test is performed to determine the implied fair value of goodwill. An impairment loss is recognized based on the amount that the carrying amount of goodwill exceeds the implied fair value. When measuring the fair value of its reporting units in the quantitative assessment, the Company uses widely accepted valuation techniques, applying a combination of the income approach (discounted cash flows) and market approach (market multiples). When preparing discounted cash flow models under the income approach, the Company uses internal forecasts to estimate future cash flows expected to be generated by the reporting units. To discount these cash flows, the Company uses the expected cost of equity, determined by using a capital asset pricing model. The Company believes the discount rates used appropriately reflect the risks and uncertainties in the financial markets generally and specifically in the Company’s internally-developed forecasts. When using market multiples under the market approach, the Company applies comparable publicly traded companies’ multiples ( e.g.
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition: The Company is a defense and security products and services company, engaged in two business areas: interactive simulation for military, law enforcement and commercial markets; and power systems and batteries for the military, commercial and medical markets. During 2017, 2016, and 2015, the Company recognized revenues (i) from the sale and customization of interactive training systems and from the maintenance services in connection with such systems (Training and Simulation Division); (ii) from the sale of batteries, chargers and adapters, and under certain development contracts; and (iii) from the sale of lifejacket lights (Power Systems Division). Revenues from certain products sold by the Power Systems Division are recognized when persuasive evidence of an agreement exists, delivery has occurred, the fee is fixed or determinable, collectability is probable, and no further obligation remains. Typically revenue is recognized, per the contract, when the transaction is entered into the U.S. Government’s Wide Area Workflow system, which occurs after the products have been accepted at the plant or when shipped. Sales to other entities are recorded in accordance with the contract, either when shipped or delivered. Normally there are no further obligations that would preclude the recognition of revenue. Additionally, certain contracts are recognized using contract accounting on a percentage of completion method. Revenues from contracts in the Training and Simulation Division and Power Systems Division that involve customization of the system to customer specifications are recognized using contract accounting on a percentage of completion method, in accordance with the “Input Method.” The amount of revenue recognized is based on the percentage to completion achieved. The percentage to completion is measured by monitoring progress using records of actual time, materials and other costs incurred to date in the project compared to the total estimated project requirement. Estimates of total project requirements are based on prior experience of customization, delivery and acceptance of the same or similar technology and are reviewed and updated regularly by management. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are first determined, in the amount of the estimated loss on the entire contract. Normally there are no further obligations that would preclude the recognition of revenue. The Company believes that the use of the percentage of completion method is appropriate for certain contracts as the Company has the ability to make reasonably dependable estimates of the extent of progress towards completion, contract revenues and contract costs. In addition, contracts executed include provisions that clearly specify the enforceable rights regarding services to be provided and received by the parties to the contracts, the consideration to be exchanged and the manner and the terms of settlement, including in cases of terminations for convenience. In all cases, the Company expects to perform its contractual obligations and its customers are expected to satisfy their obligations under the contract. Revenues from products that do not require significant customization are recognized when persuasive evidence of an agreement exists, delivery has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable. Maintenance and support revenue included in multiple element arrangements is deferred and recognized on a straight-line basis over the term of the maintenance and support services. Revenues from training are recognized when it is performed. The Vendor Specific Objective Evidence (“VSOE”) of fair value of the maintenance, training and support services is determined based on the price charged when sold separately or when renewed.
Receivables, Policy [Policy Text Block]	Trade receivables The Company records trade accounts receivable at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on the trade accounts receivable balances and charged to the provision for doubtful accounts. The Company calculates this allowance based on its history of write-offs, the level of past-due accounts based on the contractual terms of the receivables, and its relationships with, and the economic status of, its customers. During the years ended December 31, 2017 and 2016, the Company made no provisions or had any recoveries of doubtful accounts and had no reserves at either year end. The Company believes its exposure to concentrations of credit risk is limited due to the nature of its operations. Unbilled receivables include cost and gross profit earned in excess of billing. Deferred revenues include unearned amounts received under maintenance and support services, customer prepayments and billing in excess of costs and estimated earnings on uncompleted contracts.
Standard Product Warranty, Policy [Policy Text Block]	Warranty: The Company typically offers a one to two year warranty for many of its products. The specific terms and conditions of those warranties vary depending upon the product sold and country in which the Company does business. The Company estimates the costs that may be incurred under its basic limited warranty, including parts and labor, and records deferred revenue in the amount of such costs at the time product revenue is recognized in the Training and Simulation Division. In the Power Systems Division, warranty costs are estimated, accrued and recorded on the balance sheet in deferred revenues. Factors that affect the Company’s warranty liability include the number of installed units, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its reserves and adjusts the amounts as necessary. (See Note 16.)
Research, Development, and Computer Software, Policy [Policy Text Block]	Research and development cost: The Company capitalizes certain software development costs, subsequent to the establishment of technological feasibility. Based on the Company’s product development process, technological feasibility is established upon the completion of a working model or a detailed program design. Research and development costs incurred in the process of developing product improvements or new products are generally charged to expenses as incurred. Significant costs incurred by the Company between completion of the working model or a detailed program design and the point at which the product is ready for general release have been capitalized. Capitalized software costs will be amortized by the greater of the amount computed using: (i) the ratio that current gross revenues from sales of the software bears to the total of current and anticipated future gross revenues from sales of that software, or (ii) the straight-line method over the estimated useful life of the product (one to three years). The Company assesses the net realizable value of this intangible asset on a regular basis by determining whether the amortization of the asset over its remaining life can be recovered through undiscounted future operating cash flows from the specific software product sold. Based on its most recent analyses, management believes that no impairment of capitalized software development costs exists as of December 31, 2017. In 2017 and 2016, the Training and Simulation Division capitalized approximately $588,000 and $364,000, respectively, in software development costs that will be amortized on a straight-line method over 2 years, the useful life of the software.
Income Tax, Policy [Policy Text Block]	Income taxes: The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liability account balances are determined based on tax credit carryforwards and differences between the financial reporting and the tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value. Accounting standards prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. The Company must determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. Uncertain tax positions require determinations and estimated liabilities to be made based on provisions of the tax law which may be subject to change or varying interpretation. If the Company’s determinations and estimates prove to be inaccurate, the resulting adjustments could be material to the Company’s future financial statements. See Income Tax Footnote to the Consolidated Financial Statements for more information regarding income taxes (Note 13).
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of credit risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted collateral deposits and trade receivables. Cash and cash equivalents are invested mainly in U.S. dollar deposits with major Israeli and U.S. banks. Such deposits in the U.S. may be in excess of insured limits and are not insured in other jurisdictions. Management believes that the financial institutions that hold the Company’s investments are financially sound and, accordingly, minimal credit risk exists with respect to these investments. The trade receivables of the Company are mainly derived from sales to customers located primarily in the United States and Israel along with the countries listed in footnote 15.c. Management believes that credit risks are moderated by the diversity of its end customers and geographical sales areas. The Company performs ongoing credit evaluations of its customers’ financial condition. The Company had no off-balance-sheet concentration of credit risk such as foreign exchange contracts, option contracts or other foreign currency hedging arrangements as of December 31, 2017 and 2016.
Earnings Per Share, Policy [Policy Text Block]	Basic and diluted net income per share: Basic net income per share is computed based on the weighted average number of shares of common stock and participating securities outstanding during each year. Diluted net income per share includes the dilutive effect of additional potential common stock issuable under its share-based compensation plans, using the “treasury stock” method. Unvested restricted stock issued to its employees and directors are “participating securities” and as such, are included, net of estimated forfeitures, in the total shares used to calculate the Company’s basic and diluted net income per share. In the event of a net loss, unvested restricted stock awards are excluded from the calculation of both basic and diluted net loss per share. The total weighted average number of shares related to the outstanding common stock equivalents excluded from the calculations of diluted net income per share were none, none, and 602,740 for the years ended December 31, 2017, 2016, and 2015, respectively.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Accounting for stock-based compensation: Stock-based awards to employees are recognized as compensation expense based on the calculated fair value on the date of grant. The costs are amortized over the straight line vesting period. The Company granted restricted stock and restricted stock units in 2017, 2016, and 2015. The Company typically uses a 5-10% forfeiture rate for restricted stock and restricted stock units and adjusts both forfeiture rates based on historical forfeitures. Each restricted stock unit is equal to one share of Company stock and is redeemable only for stock.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value of financial instruments: The following methods and assumptions were used by the Company in estimating their fair value disclosures for financial instruments using the required three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which may require the Company to develop its own assumptions. The carrying amounts of cash and cash equivalents, restricted collateral deposits, trade and other receivables, short-term bank credit, and trade payables approximate their fair value due to the short-term maturity of such instruments (Level 1). The fair values of long-term promissory notes are estimated by discounting the future cash flows using current interest rates for loans of similar terms and maturities. The carrying amount of the long-term debt and contractual severance approximates the estimated fair values at December 31, 2017, based upon the Company’s ability to acquire similar debt or fulfill similar obligations at similar maturities (Level 3).
Postemployment Benefit Plans, Policy [Policy Text Block]	Severance pay: The Company’s liability for severance pay for its Israeli employees is calculated pursuant to Israeli severance pay law based on the most recent salary of the employees multiplied by the number of years of employment as of the balance sheet date. Israeli employees are entitled to one month’s salary for each year of employment, or a portion thereof. The Company’s liability for all of its Israeli employees is fully provided for by monthly deposits into severance pay funds held by insurance companies on behalf of the employees, insurance policies and by accrual. The fair value of these funds, which are considered Level 2 fair value measurements, is recorded as an asset in the Company’s consolidated balance sheet. In addition, according to certain employment agreements, the Company is obligated to provide for a special severance pay in addition to amounts due to certain employees pursuant to Israeli severance pay law. During the years ended December 31, 2017, 2016, and 2015, the Company had made provisions of $106,000, $1,022,000, and $143,000, respectively, for this special severance pay. As of December 31, 2017 and 2016 the unfunded severance pay amounted to $142,000 and $2,130,000, respectively. Severance expenses from continuing operations for the years ended December 31, 2017, 2016, and 2015, amounted to $728,000, $1,389,000, and $625,000, respectively. In December 2016, the Company and its former Chief Executive Officer (“former Executive”) signed an agreement whereby the Company and the former Executive agreed to early termination of the former Executive’s employment agreement. The additional expense and accrual, included above, related to this termination, were approximately $925,000 and $2,050,000, respectively.
Advertising Costs, Policy [Policy Text Block]	Advertising costs: The Company records advertising costs as incurred. Advertising expense for the years ended December 31, 2017, 2016, and 2015 was approximately $94,000, $72,000, and $159,000, respectively.
New Accounting Pronouncements, Policy [Policy Text Block]	New accounting pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as a new Topic, Accounting Standards Codification (“ASC”) 606. The new revenue recognition standard relates to revenue from contracts with customers, which, along with amendments issued in 2015 and 2016, will supersede nearly all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The underlying principle is to use a five-step analysis of transactions to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Additionally, the new standard requires enhanced disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including revenue recognition policies to identify performance obligations, assets recognized from costs incurred to obtain and fulfill a contract, and significant judgments in measurement and recognition. The Company’s task force has reviewed significant contracts with customers and the promised goods and/or services associated with the revenue streams for each segment. The Company has evaluated the distinct performance obligations and the pattern of revenue recognition of these significant contracts in advance of the implementation of the standard. In our review of contracts in each revenue stream, the Company noted no material impact in the implementation of the standard. The Company has determined the impact of adopting the standard on its control framework and notes minimal, insignificant changes to its system and other controls process. The standard, as amended, will be effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted the standard on a modified retrospective basis on January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Upon adoption, the Company expects that the ROU asset and lease liability will be recognized in the balance sheets in amounts that will be material. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new standard introduces targeted amendments intended to simplify the accounting for stock compensation. Among other things, the ASU requires all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement. The amendments are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this new standard was not material to the consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15 (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments provide guidance on eight specific cash flow issues for which the current accounting framework does not provide specific guidance. The amendments are effective for annual periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company finalized its analysis and the adoption of this guidance will not have a material impact on its consolidated financial statements and its internal controls over financial reporting. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test and requires businesses to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendments are effective for annual periods beginning after December 15, 2019 with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of its pending adoption of the new standard on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments are effective for annual periods beginning after December 15, 2017 with a limited scope of early adoption. The adoption of this new standard did not impact the Company and will apply for any future acquisitions. In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). The accounting standard allows for the optional reclassification of stranded tax effects within accumulated other comprehensive income to retained earnings that arise due to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The amount of the reclassification would reflect the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of enactment of the Tax Act and other income tax effects of the Tax Act on items remaining in accumulated other comprehensive income. The standard, will be effective for annual periods beginning after December 15, 2018, including interim periods within that reporting period with early adoption permitted. The Company is currently evaluating the impact of its pending adoption of the new standard on its consolidated financial statements.
Use of Estimates, Policy [Policy Text Block]	Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.

Reclassification, Policy [Policy Text Block]	Reclassification: Prior period amounts are reclassified, when necessary, to conform to the current period presentation.
Business Combinations Policy [Policy Text Block]	Business Combinations: The Company recognizes the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. The Company assesses the fair value of assets, including intangible assets, using a variety of methods and each asset is measured at fair value from the perspective of a market participant. The method used to estimate the fair values of intangible assets incorporates significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant’s use of the asset and the appropriate discount rates for a market participant. Assets recorded from the perspective of a market participant that are determined to not have economic use for us are expensed immediately. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred.
