                                                          "

                                                                   December 2005
- --------------------------------------------------------------------------------

                 As I write to you during the final weeks of 2005, I am watching
                 some interesting dynamics that could affect all of us in the
                 new year.

                 In 2006, we expect the Federal Reserve Board (the Fed) to stop
                 tightening short-term interest rates. After raising rates to
                 4.25% in December 2005, Fed governors, we believe, are likely
                 to hike rates at least one more time on January 31, 2006. If
                 the Fed keeps tightening, there is the possibility that
                 short-term interest rates could eventually be higher than
                 long-term rates, resulting in what is called an inverted yield
                 curve. In some cases, an inverted yield curve has been the
                 precursor of an economic downturn.

                 For the moment, however, the U.S. economy appears to be on
                 solid footing, with estimates for gross domestic product (GDP)
                 growth of about 3% for 2006. While the country is not
                 experiencing an economic boom, we can expect moderate growth in
                 the months ahead, which should translate into gains in
                 corporate earnings in the mid-single digits. Whether earnings
                 will be robust enough to support current stock market
                 valuations, however, remains uncertain. Beyond our shores,
                 international stocks outperformed U.S. equities during 2005. We
                 believe we could see a repeat of this in 2006.

                 In the gold market, prices have continued to rise, fueled by
                 high oil prices, strong investor demand, and an increase in
                 consumer purchases of jewelry. We expect these conditions to
                 persist during 2006.

                 I believe the housing market is at or near the peak in the
                 number of units sold. Inventory has grown, mortgage rates are
                 inching


                                                                               3

 . . . C O N T I N U E D
========================--------------------------------------------------------

                 upward, and some institutions have tightened their lending
                 standards. If housing prices fall, the first to feel the pain
                 could be investors who are "flipping" properties using
                 interest-only or adjustable-rate mortgages (ARMs). The dramatic
                 increase in short-term rates would be particularly painful for
                 housing investors also, especially those with ARMs and
                 interest-only mortgages.

                 Among the biggest stories of 2005 was the resiliency of
                 long-term interest rates. Instead of spiking higher, they were
                 range bound most of the year. In 2006, both short- and
                 long-term rates will continue to be a key market indicator. If
                 rates rise, bond prices will fall - hurting the bond market.

                 Going forward, two factors will have great influence on
                 long-term rates. One is inflation, which appears to be under
                 control at present. The second is the purchase of U.S. debt by
                 foreign investors, which helps us support our budget deficit.
                 With interest rates in other countries significantly lower, it
                 seems likely that foreign demand will remain strong, buoying
                 U.S. bonds. We believe that long-term rates will not spike
                 dramatically but continue to drift upward in a manageable
                 fashion.

                 In this environment, our central concern is that we are paid
                 for the risk we take in all our portfolios. It makes sense to
                 be cautious; there is some risk in the market, but risk
                 premiums are very low.

                 We will continue to look for value in our investments, examine
                 the risks, and maintain our investment discipline. From all of
                 us at USAA Investment Management Company, thank you for your
                 business and the opportunity to serve your investment needs.

                 Sincerely,

                 /s/ CHRISTOPHER W. CLAUS

                   COMMENTARY on the Fund

[PHOTO OF PAMELA BLEDSOE NOBLE]    PAMELA BLEDSOE NOBLE, CFA
                                      USAA Investment Management Company

HOW DID THE FUND PERFORM?

                 The USAA Treasury Money Market Trust had a total return of
                 1.53% for the six months ended November 30, 2005. This compares
                 to an average return of 1.35% for similar Treasury and
                 repurchase agreement (repo) money market funds ranked by
                 iMoneyNet.

HOW DID THE CONTINUING TIGHTENING CAMPAIGN BY THE FEDERAL RESERVE BOARD (THE
FED) AFFECT THE FUND?

                 The Fed raised the federal funds rate from 3% to 4% by 0.25% at
                 each of the four meetings during the reporting period. As a
                 result of the Fed's actions and our strategies, the Fund's
                 seven-day yield rose from 2.57% on May 31, 2005, to 3.53% on
                 November 30, 2005. Money market funds can be an ideal
                 fixed-income investment in a rising-rate environment.

WHAT STRATEGIES DID YOU PURSUE?

                 Our goal in this rising-rate environment is to pass along
                 higher interest rates to our shareholders as quickly as
                 possible. By investing in repurchase agreements that usually
                 mature on a daily basis, along with a ladder of Treasury bills
                 and notes, we found an effective balance for today's
                 environment. The Fund's asset mix ended the six months close to
                 where it began, with approximately 80% of net assets invested
                 in repurchase agreements and 22% in Treasury bills and other
                 government securities.

 . . . C O N T I N U E D
========================--------------------------------------------------------

HOW MANY MORE FED INTEREST-RATE INCREASES DO YOU EXPECT?

                 We expect a few more rate increases, but just how many will be
                 highly dependent on the economic data. There tends to be a lag
                 between the increased federal funds rate and the desired
                 cooling effect on the economy, so to the extent we see moderate
                 economic growth and low inflation in early 2006, the Fed should
                 have room to pause. However, the Fed controls only short-term
                 interest rates, while a larger part of the U.S. economy is
                 influenced by longer-term rates, which remain historically low.
                 We will be watching the economic data very closely to determine
                 the impact on growth, and will adjust our strategy as needed.
                 In addition, the new Fed chairman, Benjamin Bernanke, takes
                 over on February 1, 2006, adding a new dimension to the
                 interest-rate forecast.

HOW DO YOU EXPECT TO MANAGE THE FUND GOING FORWARD?

                 In the early months of 2006, we expect interest rates to
                 continue to rise, so our current mix of repurchase agreements
                 and Treasury securities will likely remain in place. If we
                 anticipate that the rise in short-term rates is coming to an
                 end, we would expect to find more value buying Treasury bills
                 and notes, effectively extending the average maturity of the
                 portfolio.

                 We thank you, our shareholders, for the confidence you've
                 placed in us, and for allowing us to help you attain your
                 short-term financial goals.

GENERAL NOTES
- --------------------------------------------------------------------------------

          Market values of securities are determined by procedures and practices
          discussed in Note 1 to the financial statements.

          The cost of securities at November 30, 2005, for federal income tax
          purposes, was approximately the same as that reported in the financial
          statements.

          The portfolio of investments category percentages shown represent the
          percentages of the investments to net assets and, in total, may not
          equal 100%.

SPECIFIC NOTES
- --------------------------------------------------------------------------------

          (a) Securities offered at a discount to face value rather than at a
              stated coupon rate. Rates represent the discount rates at purchase
              date.

          (b) Rates for U.S. Treasury notes represent the stated coupon payment
              rate at time of issuance.

          (c) Variable-rate demand note (VRDN) - provides the right to sell the
              security at face value on either that day or within the rate-reset
              period. The interest rate is adjusted at a stipulated daily,
              weekly, monthly, quarterly, or other specified time interval to a
              rate that reflects current market conditions. The effective
              maturity for this instrument is deemed to be less than 397 days in
              accordance with detailed regulatory requirements. This security is
              shown at its current rate as of November 30, 2005.

          (d) Put bond - provides the right to sell the bond at face value at
              specific tender dates prior to final maturity. The put feature
              shortens the effective maturity of the security.

          (e) Collateral on repurchase agreements is received by the Fund upon
              entering into the repurchase agreement. The collateral is

              marked-to-market daily to ensure its market value is equal to or
              in excess of the repurchase agreement price plus accrued interest.

          (f) U.S. government agency issues - mortgage-backed securities issued
              by Government National Mortgage Association (GNMA) are supported
              by the full faith and credit of the U.S. government.

          (g) U.S. Treasury inflation-indexed notes/bonds - designed to provide
              a real rate of return after being adjusted over time to reflect
              the impact of inflation. Their principal value periodically
              adjusts to the rate of inflation. They trade at the prevailing
              real, or after-inflation, interest rates. The U.S. Treasury
              guarantees repayment of these securities of at least their face
              value in the event of sustained deflation or a drop in prices.
              Inflation adjustments to the face value of these securities are
              included in interest income.

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2005 (UNAUDITED)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

          USAA INVESTMENT TRUST (the Trust), registered under the Investment
          Company Act of 1940 (the 1940 Act), as amended, is an open-end
          management investment company organized as a Massachusetts business
          trust consisting of 10 separate funds. The information presented in
          this semiannual report pertains only to the USAA Treasury Money Market
          Trust (the Fund), which is classified as diversified under the 1940
          Act. The Fund's investment objective is to provide maximum current
          income while maintaining the highest degree of safety and liquidity.

             A. SECURITY VALUATION - The value of each security is determined
                (as of the close of trading on the New York Stock Exchange on
                each business day the exchange is open) as set forth below:

                1. Pursuant to Rule 2a-7 under the 1940 Act, securities in the
                   Fund are valued at amortized cost, which approximates market
                   value. This method values a security at its cost on the date
                   of purchase and, thereafter, assumes a constant amortization
                   to maturity of any premiums or discounts. Repurchase
                   agreements are valued at cost.

                2. Securities for which valuations are not readily available or
                   are considered unreliable are valued in good faith at fair
                   value, using methods determined by USAA Investment Management
                   Company (the Manager), an affiliate of the Fund, under
                   valuation procedures and procedures to stabilize net asset
                   value approved by the Trust's Board of Trustees.

             B. FEDERAL TAXES - The Fund's policy is to comply with the
                requirements of the Internal Revenue Code applicable to
                regulated investment companies and to distribute substantially
                all of its income to its shareholders. Therefore, no federal
                income tax provision is required.


                                                                              17

           (continued)

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2005 (UNAUDITED)

             C. INVESTMENTS IN SECURITIES - Security transactions are accounted
                for on the date the securities are purchased or sold (trade
                date). Gains or losses from sales of investment securities are
                computed on the identified cost basis. Interest income is
                recorded daily on the accrual basis. Discounts and premiums on
                securities are amortized over the life of the respective
                securities using the straight-line method.

             D. REPURCHASE AGREEMENTS - The Fund may enter into repurchase
                agreements with commercial banks or recognized security dealers.
                These agreements are collateralized by obligations issued or
                guaranteed as to both principal and interest by the U.S.
                government, its agencies, or its instrumentalities. Obligations
                pledged as collateral are required to maintain a value equal to
                or in excess of the repurchase agreement price plus accrued
                interest and are held by the Fund, either through its regular
                custodian or through a special "tri-party" custodian that
                maintains separate accounts for both the Fund and its
                counterparty, until maturity of the repurchase agreement. The
                Fund's Manager monitors the creditworthiness of sellers with
                which the Fund may enter into repurchase agreements.

             E. SECURITIES PURCHASED ON A WHEN-ISSUED BASIS - Delivery and
                payment for securities that have been purchased by the Fund on a
                when-issued basis can take place a month or more after the trade
                date. During the period prior to settlement, these securities do
                not earn interest, are subject to market fluctuation, and may
                increase or decrease in value prior to their delivery. The Fund
                maintains segregated assets with a market value equal to or
                greater than the amount of its purchase commitments. The Fund
                had no when-issued commitments as of November 30, 2005.

             F. EXPENSES PAID INDIRECTLY - Through arrangements with the Fund's
                custodian and other banks utilized by the Fund for cash
                management purposes, realized credits, if any, generated from
                cash

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2005 (UNAUDITED)

                balances in the Fund's bank accounts are used to reduce the
                Fund's expenses. For the six-month period ended November 30,
                2005, these custodian and other bank credits reduced the Fund's
                expenses by $3,000.

             G. INDEMNIFICATIONS - Under the Trust's organizational documents,
                its officers and trustees are indemnified against certain
                liabilities arising out of the performance of their duties to
                the Trust. In addition, in the normal course of business the
                Trust enters into contracts that contain a variety of
                representations and warranties that provide general
                indemnifications. The Trust's maximum exposure under these
                arrangements is unknown, as this would involve future claims
                that may be made against the Trust that have not yet occurred.
                However, the Trust expects the risk of loss to be remote.

             H. USE OF ESTIMATES - The preparation of financial statements in
                conformity with U.S. generally accepted accounting principles
                requires management to make estimates and assumptions that may
                affect the reported amounts in the financial statements.

(2) LINES OF CREDIT
- --------------------------------------------------------------------------------

          The Fund participates in a joint, short-term, revolving, committed
          loan agreement of $300 million with USAA Capital Corporation (CAPCO),
          an affiliate of the Manager. The purpose of the agreement is to meet
          temporary or emergency cash needs, including redemption requests that
          might otherwise require the untimely disposition of securities.
          Subject to availability under the agreement, the Fund may borrow from
          CAPCO an amount up to 5% of the Fund's total assets at a rate per
          annum equal to the rate at which CAPCO obtains funding in the capital
          markets, with no markup.

          The USAA funds that are party to the loan agreement are assessed
          facility fees by CAPCO based on the funds' assessed proportionate


                                                                              19

NOVEMBER 30, 2005 (UNAUDITED)

          share of CAPCO's operating expenses related to obtaining and
          maintaining CAPCO's funding programs in total (in no event to exceed
          0.09% annually of the $300 million loan agreement). The facility fees
          are allocated among the funds based on their respective average net
          assets for the period.

          For the six-month period ended November 30, 2005, the Fund paid CAPCO
          facility fees of less than $500, which represents 0.6% of total fees
          paid to CAPCO by the USAA funds. The Fund had no borrowings under this
          agreement during the six-month period ended November 30, 2005.

(3) DISTRIBUTIONS
- --------------------------------------------------------------------------------

          The tax basis of distributions and accumulated undistributed net
          investment income will be determined based upon the Fund's tax
          year-end of May 31, 2006, in accordance with applicable tax law.

          Net investment income is accrued daily as dividends and distributed to
          shareholders monthly. Distributions of realized gains from security
          transactions not offset by capital losses are made annually in the
          succeeding fiscal year or as otherwise required to avoid the payment
          of federal taxes.

(4) TRANSACTIONS WITH MANAGER
- --------------------------------------------------------------------------------

             A. MANAGEMENT FEES - The Manager carries out the Fund's investment
                policies and manages the Fund's portfolio. The Fund's management
                fees are accrued daily and paid monthly at an annualized rate of
                0.125% of the Fund's average net assets for the fiscal year. For
                the six-month period ended November 30, 2005, the Fund incurred
                management fees, paid or payable to the Manager, of $112,000.

             B. ADMINISTRATION AND SERVICING FEES - The Manager provides certain
                administration and shareholder servicing functions for the Fund.
                For such services, the Manager receives a fee accrued

                daily and paid monthly at an annualized rate of 0.10% of the
                Fund's average net assets. For the six-month period ended
                November 30, 2005, the Fund incurred administration and
                servicing fees, paid or payable to the Manager, of $90,000.

                In addition to the services provided under its Administration
                and Servicing Agreement with the Fund, the Manager also provides
                certain legal and tax services for the benefit of the Fund. The
                Trust's Board of Trustees has approved the reimbursement of
                these expenses incurred by the Manager. For the six-month period
                ended November 30, 2005, the Fund reimbursed the Manager $6,000
                for these legal and tax services. These expenses are included in
                the professional fees expenses on the Fund's statement of
                operations.

             C. TRANSFER AGENT'S FEES - USAA Transfer Agency Company, d/b/a USAA
                Shareholder Account Services (SAS), an affiliate of the Manager,
                provides transfer agent services to the Fund based on an annual
                charge of $25.50 per shareholder account plus out-of-pocket
                expenses. The Fund also pays SAS fees that are related to the
                administration and servicing of accounts that are traded on an
                omnibus basis. For the six-month period ended November 30, 2005,
                the Fund incurred transfer agent's fees, paid or payable to SAS,
                of $117,000.

             D. UNDERWRITING SERVICES - The Manager provides exclusive
                underwriting and distribution of the Fund's shares on a
                continuing best-efforts basis. The Manager receives no
                commissions or fees for this service.

(5) TRANSACTIONS WITH AFFILIATES
- --------------------------------------------------------------------------------

          Certain trustees and officers of the Fund are also directors,
          officers, and/or employees of the Manager. None of the affiliated
          trustees or Fund officers received any compensation from the Fund.


                                                                              21

               EXAMPLE

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2005 (UNAUDITED)

EXAMPLE
- --------------------------------------------------------------------------------

          As a shareholder of the Fund, you incur two types of costs: direct
          costs, such as wire fees, redemption fees, and low balance fees; and
          indirect costs, including management fees, transfer agency fees, and
          other Fund operating expenses. This example is intended to help you
          understand your indirect costs, also referred to as "ongoing costs"
          (in dollars), of investing in the Fund and to compare these costs with
          the ongoing costs of investing in other mutual funds.

          The example is based on an investment of $1,000 invested at the
          beginning of the period and held for the entire six-month period of
          June 1, 2005, through November 30, 2005.

ACTUAL EXPENSES
- --------------------------------------------------------------------------------

          The first line of the table on the next page provides information
          about actual account values and actual expenses. You may use the
          information in this line, together with the amount you invested at the
          beginning of the period, to estimate the expenses that you paid over
          the period. Simply divide your account value by $1,000 (for example,
          an $8,600 account value divided by $1,000 = 8.6), then multiply the
          result by the number in the first line under the heading "Expenses
          Paid During Period" to estimate the expenses you paid on your account
          during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
- --------------------------------------------------------------------------------

          The second line of the table provides information about hypothetical
          account values and hypothetical expenses based on the Fund's actual
          expense ratio and an assumed rate of return of 5% per year before
          expenses, which is not the Fund's actual return. The hypothetical
          account values and expenses may not be used to estimate the actual
          ending account balance or expenses you paid for the period. You may


                                                                              23

               (continued)

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2005 (UNAUDITED)

          use this information to compare the ongoing costs of investing in the
          Fund and other funds. To do so, compare this 5% hypothetical example
          with the 5% hypothetical examples that appear in the shareholder
          reports of other funds.

          Please note that the expenses shown in the table are meant to
          highlight your ongoing costs only and do not reflect any direct costs,
          such as wire fees, redemption fees, or low balance fees. Therefore,
          the second line of the table is useful in comparing ongoing costs
          only, and will not help you determine the relative total costs of
          owning different funds. In addition, if these direct costs were
          included, your costs would have been higher.



                                                                                EXPENSES PAID
                                      BEGINNING             ENDING              DURING PERIOD*
                                    ACCOUNT VALUE        ACCOUNT VALUE          JUNE 1, 2005-
                                    JUNE 1, 2005       NOVEMBER 30, 2005       NOVEMBER 30, 2005
                                    ------------------------------------------------------------
                                                                            
          Actual                      $1,000.00            $1,015.30                 $2.30
          Hypothetical
          (5% return before expenses)  1,000.00             1,022.79                  2.30


          *Expenses are equal to the Fund's annualized expense ratio of 0.46%,
           which is net of any expenses paid indirectly, multiplied by the
           average account value over the period, multiplied by 183 days/365
           days (to reflect the one-half year period). The Fund's ending account
           value on the first line in the table is based on its actual total
           return of 1.53% for the six-month period of June 1, 2005, through
           November 30, 2005.

The  principal  executive  officer  and  principal  financial  officer  of  USAA
