                                           WE MAY NOT HAVE REACHED THE PEAK

[PHOTO OF CHRISTOPHER W. CLAUS]              BUT WE HAVE SEEN A REMARKABLE

- --------------------------------------------------------------------------------

                 Economic reports confirm that the U.S. and global economies
                 began a robust expansion early in the autumn of 2003. We are
                 finally seeing the results of the fiscal and monetary policies
                 that were implemented to stimulate economic growth. The economy
                 is benefiting from the lowest short-term interest rates in
                 decades, reduced marginal tax rates, and increased government
                 spending. Productivity has increased to its highest level in 20
                 years, and corporate America is starting once again to invest
                 in capital goods and to add employees to its payrolls. Finally,
                 American goods and services are more competitive in global
                 markets because foreign currencies have gained strength over
                 the U.S. dollar.

                 All of these positive developments have translated into the
                 growth of the gross domestic product (GDP) and improved
                 corporate profitability, both of which have significantly
                 driven up stock prices. So we're left with the obvious
                 question: Can the economy keep growing fast enough and long
                 enough to support existing equity valuations and to provide for
                 higher stock prices?

                 While no one can predict what will happen, we do believe that
                 market volatility will remain the norm rather than the
                 exception. We may not have reached the peak of the current
                 cyclical bull market, but we have seen a remarkable run-up in
                 stock prices. Consequently, we would not be surprised to see
                 some form of


                                                                               3

                 consolidation before stocks try to break through resistance
                 levels - assuming, of course, that the economy keeps growing,
                 more new jobs are created, corporate profitability continues to
                 improve, and short-term rates (which are expected to increase
                 in 2004) do not spike dramatically.

                 Whatever happens, the most effective strategy in any market
                 cycle is a well-thought-out investment plan that incorporates
                 asset allocation, diversification, and a true understanding of
                 your personal tolerance for risk - all matched to your
                 investment goals.

                 At USAA, we remain committed to helping you with your goals. We
                 will continue to provide you with outstanding resources - a
                 market-tested portfolio management team, world-class service,
                 and no-load mutual funds without excessive fees, sales loads,
                 or contractual plans.

                 For all of us here at USAA, I would like to thank you for your
                 business.

                 Sincerely,

HOW DID THE FUND PERFORM?

                 The USAA Treasury Money Market Trust had a total return of
                 0.33% for the six-month period ended November 30, 2003. This
                 compares to an average return of 0.17% for similar Treasury
                 and repurchase agreement (repo) money market funds ranked by
                 iMoneyNet, Inc. This performance placed the Fund in the top 6%
                 of its peer group as ranked by iMoneyNet.

WHAT WERE THE MAJOR DRIVERS OF THE FUND'S YIELD DURING THE SIX-MONTH PERIOD?

                 The interest-rate policy of the Federal Reserve Board (the
                 Fed), as well as the market's pricing of potential Fed moves,
                 had the greatest impact. The Fed adjusted rates one time
                 during the period, on June 25, 2003, cutting the federal funds
                 rate from 1.25% to 1%. This move was widely anticipated, so
                 the impact on the market was rather muted. The Fund's yield
                 reflects the fact that the federal funds rate is currently at
                 a 45-year low.

                 PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

                 IMONEYNET, INC. RANKED THE FUND 5 OUT OF 90 TREASURY RETAIL

                          COMMENTARY on the Fund

HOW DID YOU MANAGE THE FUND IN THIS ENVIRONMENT?

                 The Fund continued to pursue a dual strategy to maximize yield
                 while maintaining flexibility to respond to changing market
                 conditions. To stabilize the yield in the low-rate environment,
                 we invested in a portfolio of U.S. Treasury securities with
                 maturities from one month to one year. The remaining assets
                 were invested in repos (backed by Treasury securities). To
                 provide the highest possible yield for shareholders, we
                 continually looked for opportunities to buy Treasuries and
                 lengthen the Fund's maturity when market conditions warranted.

                 Looking forward, we think the economic recovery will continue
                 to strengthen, which will eventually lead to higher interest
                 rates. This should be reflected in the Fund's yield.

HOW DOES THE FUND MANAGE TO OUTPERFORM ITS PEER GROUP WHEN INTEREST RATES ARE SO
LOW?

                 We are generally able to seize opportunities in the Treasury
                 market, and our low expense ratio provides more income to pass
                 on to you, our shareholders. We're doing all we can as
                 managers to support the Fund's yield, while keeping in mind
                 that the primary purpose of money market funds is to provide
                 liquidity and stability. We thank you for the confidence
                 you've placed in us. We're working hard every day to continue
                 to earn your trust.

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, 2003, for federal income tax
         purposes, was approximately the same as that reported in the financial
         statements.

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

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

         (a) Rates for U.S. Treasury bills represent the discount rate 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, on any
             business day, 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 weekly or quarterly 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, 2003.

         (d) 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 resale price of the repurchase agreement.

USAA TREASURY MONEY MARKET TRUST
NOVEMBER 30, 2003 (UNAUDITED)

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

         USAA INVESTMENT TRUST (the Trust), registered under the Investment
         Company Act of 1940, as amended, is a diversified, open-end
         management investment company organized as a Massachusetts business
         trust consisting of nine separate funds. The information presented in
         this semiannual report pertains only to the USAA Treasury Money Market
         Trust (the Fund). 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 Investment Company Act of
                  1940, securities in the Fund are stated at amortized cost,
                  which approximates market value. 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
                  (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.

            C. INVESTMENTS IN SECURITIES - Security transactions are accounted
               for on the date the securities are purchased or sold (trade
               date). Gain or loss from sales of investment securities is
               computed on the identified cost basis. Interest income is
               recorded daily on the


                                                                             17

               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 resale price of the repurchase agreement 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. EXPENSES PAID INDIRECTLY - Through fee-offset arrangements with
               certain of the Fund's service providers, realized credits, if
               any, are used to reduce the Fund's expenses. For the six-month
               period ended November 30, 2003, these fee-offset arrangements
               reduced the Fund's expenses by $3,000.

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

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

         The Fund participates with other USAA funds in two joint, short-term,
         revolving, committed loan agreements totaling $500 million: $400
         million with USAA Capital Corporation (CAPCO), an affiliate of the
         Manager, and $100 million with Bank of America. The purpose of the
         agreements

         is to meet temporary or emergency cash needs, including redemption
         requests that might otherwise require the untimely disposition of
         securities.

         Subject to availability under its agreement with CAPCO, the Fund may
         borrow from CAPCO an amount up to 5% of the Fund's total assets at
         CAPCO's borrowing rate with no markup. Subject to availability under
         its agreement with Bank of America, the Fund may borrow from Bank of
         America, at Bank of America's borrowing rate plus a 0.50% markup, an
         amount which, when added to outstanding borrowings under the CAPCO
         agreement, does not exceed 25% of the Fund's total assets.

         The USAA funds that are party to the loan agreements are assessed
         facility fees in aggregate by Bank of America in an annual amount
         equal to 0.09% of the $100 million loan agreement, whether used or
         not, and by CAPCO based on the funds' assessed proportionate 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 $400 million loan agreement). The facility fees are
         allocated among the funds based on their respective average net assets
         for the period. The Fund had no borrowings under either of these
         agreements during the six-month period ended November 30, 2003.

(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, 2004, 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.


                                                                             19

THROUGH OUR ONGOING EFFORTS TO REDUCE EXPENSES, YOUR REPORT MAILINGS ARE
STREAMLINED. WE DEVELOP MAILING LISTS USING CRITERIA SUCH AS ADDRESS, MEMBER
NUMBER, AND SURNAME TO SEND ONE REPORT TO EACH HOUSEHOLD INSTEAD OF SENDING A
REPORT TO EVERY REGISTERED OWNER. THIS PRACTICE IS DESIGNED TO REDUCE DUPLICATE
COPIES AND SAVE PAPER AND POSTAGE COSTS TO THE FUND. IF YOU PREFER NOT TO
PARTICIPATE IN STREAMLINING AND WOULD LIKE TO CONTINUE RECEIVING ONE REPORT PER
REGISTERED ACCOUNT OWNER, PLEASE CALL US AND WE WILL BEGIN YOUR INDIVIDUAL
DELIVERY WITHIN 30 DAYS OF YOUR REQUEST.

COPIES OF THE MANAGER'S PROXY VOTING POLICIES AND PROCEDURES ARE AVAILABLE
WITHOUT CHARGE (I) BY CALLING 1-800-531-8448; (II) AT USAA.COM; AND (III) ON THE
SEC'S WEB SITE AT HTTP://WWW.SEC.GOV.
