What many consider near perfect conditions--a firm economy, low inflation
and relatively stable long-term interest rates--have prevailed over the last
six months. As the second quarter came to a close on June 30, the Dow reached
7672.79, a year-to-date gain of 1224.52 points and an increase of 18.99% over
1996's year-end close.

Again, USAA Life's Variable Annuity fund accounts mirrored the market--
posting solid returns over the past six months.  An overview of historical
performance, as well as accumulation unit values, can be found on page A-7 of
this Report. To receive accumulation unit value updates 24-hours-a-day,
seven-days-a week, call our toll-free Quoteline at 1-800-531-8233 (498-6860
in San Antonio).

Also during the first half of 1997, USAA Life issued 1,295 contracts bringing
the total number of contractowners to 4,968.

PUTTING THINGS IN PERSPECTIVE
- -----------------------------

The '90s will undoubtedly be remembered for having one of the most relentless
bull markets. Volatility, heavy trading late in the day, and constantly changing
"record highs" are just a few of the trends which emerged. Statistics released
by Washington used to be the catalyst for market swings, but now, more than ever
before, market activity is also being driven by sentiment and perception. Many
find it hard to remain focused in such an environment. Here are a few points you
may want to consider:

 . The impact of what we have thought of as large point declines has become far
  less significant to the total value of today's market. With the Dow's rise
  over the last few years, these point declines represent a smaller percentage
  decline.

 . If your goals are long term, price decreases shouldn't impact the overall
  future value of your contract.

 . Diversification is the basis for a sound and balanced strategy. A correctly
  diversified portfolio can minimize risk, while at the same time provide
  greater potential for optimizing returns. By their very nature, variable
  annuity fund accounts are diversified. The fund accounts invest in an
  underlying fund whose portfolio holds a mix of stocks and/or bonds. To further
  diversify your portfolio, allocate money to a number of fund accounts with
  different levels of risk and include those with international investment
  programs as well as domestic ones.

 . USAA Life's Variable Annuity provides flexibility to change investment
  strategies, enabling you to move money among the fund accounts without
  creating a taxable event. And, there is no contract fee for moving money among
  any of our nine variable fund accounts.

 . Make saving a habit. If you haven't already done so, put investing on
  autopilot by establishing an Automatic Payment Plan (APP).

  APP authorizes USAA Life to withdraw a specified amount of money from your
  bank or credit union each month, automatically adding to the value of your
  Variable Annuity contract. To further simplify the process, we've enclosed an
  APP form and return envelope in case you're interested. If you already have
  APP in place and wish to increase contributions, simply call a USAA LIFE
  SERVICE REPRESENTATIVE AT 1-800-531-4265.

 . Instead of trying to "time" the market, consider Dollar Cost Averaging. It
  allows you to build a long-term financial plan by systematically allocating a
  fixed dollar amount or a specified percentage to your contract. Through the
  years, this strategy could produce a better return than any attempt to
  selectively time the market with occasional purchases. Even though it has
  proven to be an effective tactic, keep in mind that there is no guarantee
  Dollar Cost Averaging will result in a profit or protect against a loss.
  Systematic investing involves continuous investment in securities regardless
  of the fluctuating price levels of these securities. Always consider your
  ability to continue through periods of both low and high price levels.

 . If adding to your contract at your discretion, take advantage of dips in
  variable annuity unit prices when the market is down.

 . If altering your investment strategy, consider incremental changes. Try to
  avoid making radical changes to your portfolio.

 . If fund account performance is driving your investing decisions, consider both
  current and historical performance. A top performer today may not have the
  same historical track record and vice versa. Also keep in mind that past
  performance is no guarantee of future returns.

LOOKING FORWARD
- ---------------

The Variable Annuity you purchased from USAA Life is an innovative product
which offers options, flexibility, and diversification at a fair price. We
strive to evaluate and update our Variable Annuity contract as much as
possible. For example, we recently added two fund accounts to our contract
because we know how important it is to have choices when designing a
financial portfolio.

So now, if you're intrigued by foreign markets explore our USAA Life VA
International Fund Account. Or, if you prefer the challenges of high risks
with opportunities for rapid growth, consider our USAA Life VA Aggressive
Growth Fund Account.  Both of these options are managed by our own USAA
Investment Management Company (IMCO) portfolio managers and mirror similarly
named public mutual funds offered by IMCO.

Investment objectives and strategies for these two fund accounts, as well as
all of the others, are discussed later in this Report. I encourage you to
review these commentaries as they provide insight which may be helpful in
making investing decisions.

As always, simply call a USAA Life Account Representative to discuss this
Report or your own personal financial situation.

/1/  Foreign investing is subject to additional risks, such as currency
     fluctuations, market illiquidity, and political instability, which are
     discussed in the Variable Annuity prospectus.

/2/  Total returns for periods of less than one year are not annualized. These
     two-month returns are cumulative.

The AUV total return figures are computed in accordance with a formula
prescribed by the Securities and Exchange Commission which includes the
deduction of all contract charges. The performance data quoted represent past
performance and do not represent the actual experience of amounts invested by a
particular owner. Past performance is not a guarantee for future returns. An
investment in the USAA Life VA Money Market Fund is neither insured nor
guaranteed by the U.S. Government. There can be no assurance that the Fund will
be able to maintain a stable net asset value of $1. The principal value
contributed to the other fund accounts will fluctuate. When variable annuity
accumulation units are redeemed, they may be worth more or less than their
original cost.

                SEPARATE ACCOUNT OF USAA LIFE INSURANCE COMPANY

                         NOTES TO FINANCIAL STATEMENTS

                                                       June 30, 1997 (Unaudited)

1)   ORGANIZATION

The Separate Account of USAA Life Insurance Company (the Separate Account) is
registered under the Investment Company Act of 1940, as amended, as a segregated
unit investment account of USAA Life Insurance Company (USAA Life), a wholly
owned subsidiary of United Services Automobile Association (USAA).

The Separate Account is divided into nine variable annuity fund accounts, each
of which invests in a corresponding fund. The funds' objectives can be found on
page A-7 in this report.

The fund accounts available within the Separate Account include: the USAA Life
Variable Annuity (VA) Money Market Fund Account, USAA Life VA Income Fund
Account, USAA Life VA Growth and Income Fund Account, USAA Life VA World Growth
Fund Account, USAA Life VA Diversified Assets Fund Account, USAA Life VA
Aggressive Growth Fund Account, and USAA Life VA International Fund Account; the
Fund Account of the Capital Growth Portfolio-Class A shares of the Scudder
Variable Life Investment Fund (Scudder VLIF Capital Growth Portfolio Fund
Account); and the Fund Account of the American Growth Portfolio of the Alger
American Fund (Alger American Growth Portfolio Fund Account).

The assets of the Separate Account are the property of USAA Life and are not
chargeable with liabilities arising out of any other business of USAA Life.

2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SECURITY VALUATION

Investments in mutual fund securities are carried in the Statement of Assets and
Liabilities at net asset value as reported by the fund. Gains or losses on
securities transactions are determined on the basis of the first-in first-out
(FIFO) cost method. Security transactions are recorded on the trade date.
Dividend income, if any, is recorded on ex-dividend date. 

ANNUITY RESERVES

Annuity reserves for contracts in the payout phase are comprised of net contract
purchase payments, less benefits. These reserves are adjusted daily for the net
investment income and net realized gain (loss) and change in unrealized
appreciation/depreciation on investments. The mortality risk is fully borne by
USAA Life. The mortality calculations are based on the 1983a Individual
Annuitant Mortality Table at 3.0% interest. This may result in additional
amounts being transferred into the Separate Account by USAA Life to cover
greater longevity of annuitants than expected. Conversely, if reserves exceed
amounts required, transfers may be made to USAA Life.

DISTRIBUTIONS

The net investment income (loss) and realized capital gains of the Separate
Account are not distributed, but instead are retained and reinvested for the
benefit of unit owners.

FEDERAL INCOME TAX

Operations of the Separate Account are included in the federal income tax return
of USAA Life, which is taxed as a "life insurance company" under the Internal
Revenue Code. Under current federal income tax law, no income taxes are payable
with respect to operation of the Separate Account.

UNIT VALUE

For financial reporting purposes, amounts have been rounded to the nearest
thousand dollars, except for per unit amounts, which may result in minor
rounding differences. Per unit amounts are calculated based on precise amounts.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
may affect the reported amounts in the financial statements.

3)   RELATED PARTY TRANSACTIONS

During the six-month period ended June 30, 1997, advisory fees of $208,002 were
paid or payable to USAA Investment Management Company (USAA IMCO) by the funds
of the USAA Life Investment Trust (the Trust). USAA IMCO is indirectly wholly
owned by USAA. The funds' advisory fees are computed on an annualized rate of
0.20% of the monthly average net assets for each calendar month of each fund of
the Trust except for the USAA Life VA Aggressive Growth Fund, which accrues at
an annualized rate of 0.50%, and USAA Life VA International Fund, which accrues
at an annualized rate of 0.65%. USAA Life, out of its general account, has
agreed to reimburse USAA IMCO for the expenses it incurs in rendering services
to the Trust, but only to the extent these expenses exceed the amount of the
preceding advisory fees.

4)   EXPENSES

A mortality and expense risk charge is deducted by USAA Life from the Separate
Account on a daily basis which is equal, on an annual basis, to 1.05% of the
daily net asset value of each variable annuity fund account. The mortality risks
assumed by USAA Life arise from its contractual obligation to make annuity
payments after the annuity date for the life of the annuitant in accordance with
annuity rates guaranteed in the contracts under distribution options that
involve life contingencies. USAA Life will also assume a mortality risk by its
contractual obligation to pay a death benefit upon the death of an annuitant or
contractowner prior to the Distribution Phase. The expense risk assumed by USAA
Life is that the costs of administering the contracts and the Separate Account
may exceed the amount recovered from the contract maintenance and administration
expense charge. The mortality and expense risk charge is guaranteed by USAA Life
and cannot be increased.

The following expenses are charged to reimburse USAA Life for the expenses it
incurs in the establishment and maintenance of the Contracts and each variable
annuity fund account. USAA Life assesses each variable annuity fund account a
daily charge at an annualized rate of 0.10% of the average daily net assets of
each variable annuity fund account. Beginning on the first anniversary of the
effective date, and on each anniversary thereafter, a maintenance charge of $30
is deducted by USAA Life from the accumulated value of each contract. This
charge will apply only while the contract is in the accumulation phase. For the
six-month period ended June 30, 1997, contract maintenance charges totaled
$56,282.

Any premium tax levied by a state or government entity with respect to the
Separate Account will be charged against the contract.

                 AN OVERVIEW                    JUNE 30, 1997


COMPARISON OF FUND TO BENCHMARK


[GRAPH APPEARS HERE]



DATA REPRESENT THE LAST TUESDAY OF EACH MONTH.

The graph above tracks the USAA Life VA Money Market Fund's 7-day yield compared
to a benchmark -- IBC/Donoghue's Money Fund Averages(TM)/First Tier, an average 
of all major money market fund 7-day yields.

Information for the benchmark is based on a full calendar year in 1995, whereas
the VA Money Market Fund yields are based on a starting date of January 5,
1995--the inception date of this Fund. This comparison is for illustrative
purposes only.

GENERAL DISCUSSION 
by Portfolio Manager Pam Bledsoe

CURRENT MARKET CONDITIONS

At the March 25, 1997 policy meeting, the Federal Open Market Committee (FOMC)
raised short-term interest rates 25 basis points to 5.50%. This widely
anticipated action was made in response to a persistently strong economy that
was viewed as "increasing the risk of inflation". Immediately after the March
meeting, the marketplace was convinced that the FOMC would increase rates again
in May. But when softer economic numbers were released in the following weeks,
attention quickly shifted to the July meeting. As economic statistics continue
to show a contradictory blend of slowing versus robust factors, the financial
marketplace is focusing on the possibility that additional rate increases will
be announced at future FOMC meetings.

STRATEGY

Our strategy is governed by the Variable Annuity contract's free-look period.
This necessitates that we manage the VA Money Market Fund with relatively short
maturities, usually 7 to 16 days. The portfolio contains three types of
holdings: Variable Rate Demand Notes, U.S. Government Agency Discount Notes, and
Commercial Paper. The mix among these types of holdings varies depending on
their availability and the cash needs of the Fund.

An investment in this Fund is neither insured nor guaranteed by the U.S.
Government and there is no assurance that the Fund will maintain a stable net
asset value of $1.

INVESTMENT PROGRAM:

This Fund invests in a diversified portfolio of high-quality U.S. 
dollar-denominated debt instruments that present minimal credit risk with 
remaining maturities of 397 days or less.

  This six-month return is cumulative.

The total return calculations found in this section are calculated at the Fund's
investment level and reflect the change in the net asset value (NAV), the
reinvestment of income dividends, and the deductions of Fund expenses. More
specific information regarding the Fund expenses can be found in the Variable
Annuity prospectus. These NAV total return calculations represent past
performance which is no guarantee of future returns.

DATA REPRESENT THE LAST BUSINESS DAY OF EACH MONTH.


The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Income Fund to two industry indexes which most closely resemble
the holdings of this Fund.  The Lehman Brothers Aggregate Bond Index is an 
unmanaged index made up of the government/corporate index, the mortgage-backed
securities index, and the asset-backed securities index.  The Lipper A Rated 
Bond Fund Index is an unmanaged index made up of funds investing in corporate 
debt issues rated A or better or government issues.  The calculations for the 
Lehman Brothers and Lipper Indexes are based on a full calendar year in 1995, 
whereas the VA Income Fund calculations are based on a starting date of 
January 5, 1995 -- the inception date of this Fund.  This comparison is for 
illustrative purposes only.

GENERAL DISCUSSION

MARKET CONDITIONS

Rising interest rates and bond market volatility continue to frustrate bond
investors. The fluctuating path of long-term interest rates in this six-month
reporting period can be seen in the chart below which shows daily yields for the
30-year U.S. Treasury bond. The low point was reached in mid-February, the high
point came two months later, and the subsequent decline to June 30, 1997 put
interest rates somewhat higher than their beginning level. The resulting up and
down bond value changes are not easily ignored;

however, the income continues and is reinvested at the varying bond prices.  
This produces the compounding of returns leading to capital accumulation which 
is the benefit that accrues to bond investors.  This compounding is enhanced in 
a tax-deferred environment.

PORTFOLIO

We made adjustments which should reduce some of the portfolio's volatility
without reducing income. Reductions have been made in U.S. Treasury bonds and
mortgage pass-through securities in favor of some intermediate maturity
corporate bonds. Common stocks have also been reduced and preferred stocks
increased. Currently, the VA Income Fund's investment mix as percentages of net
assets is 16.0% in U.S. Treasury bonds, 54.1% in agency mortgage pass-through
securities, 11.4% in corporate bonds, 9.1% in preferred stocks, and 8.3% in high
yield common stocks.

OUTLOOK

Continued strength in the economy plus the Federal Reserve's tightening action
in March have caused the ongoing volatility in the bond market. Although further
tightening by the Federal Reserve is unlikely in the short run, convincing
evidence that the economy is slowing will be required before we can expect a
further decline in interest rates. Meanwhile, we continue to concentrate on
producing a high level of income for the fund.

COMPARISON OF FUND TO BENCHMARK


[GRAPH APPEARS HERE]



DATA REPRESENT THE LAST BUSINESS DAY OF EACH MONTH.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Growth and Income Fund to the S&P 500 Index. The S&P 500 Index 
is an unmanaged index representing the average performance of a group of 500 
widely held, publicly traded stocks. It is not possible to invest directly in 
the S&P 500 Index.

The calculations for the S&P 500 Index are based on a full calendar year in

GENERAL DISCUSSION
by Portfolio Manager R. David Ullom

On a recent research trip to New Orleans, I was reminded of the popular
expression, "Laissez les bon temps roulez" (let the good times roll). It seems
that this expression aptly describes the recent activity in the U.S. equity
market. The "good times", or strong rise in the equity markets, continue despite
warnings from a host of market experts, including the Chairman of the Federal
Reserve Board.

As much as we would like the equity markets and the VA Growth and Income Fund to
continue their strong appreciation, the good times will not continue forever. At
some point, the current pace of economic expansion and market appreciation will
taper off. However, as we have remarked in previous reports, our strategy for
managing the Fund is not predicated on a particular economic or market outlook.

The Fund's performance was positively impacted by investments in manufacturing -
diversified industries (Hillenbrand Industries), heavy duty trucks & parts
(Aeroquip-Vickers); machinery - diversified (Deere & Co. and BW/IP, Inc.);
insurance (American International Group, Allstate Corp., and Everest
Reinsurance); finance related (Morgan Stanley, Dean Witter and Associates First
Capital); electronics - semiconductors (Applied Materials and Silicon Valley
Group); and leisure time (Brunswick). Note that this list of companies whose
stocks did well is quite diversified and is representative of our investment
approach of purchasing stocks based on value.

INVESTMENT PROGRAM:

Not less than 65% of its assets are invested in a diversified portfolio of 
dividend-paying common stocks and convertible securities of companies that offer
the prospect for growth of earnings.

               AN OVERVIEW (CONTINUED)             JUNE 30, 1997


Investments that had a negative impact on performance were primarily in
commodity-oriented industries, such as chemicals (Dow and Union Carbide); oils
(Occidental Petroleum, Unocal, Gulf Canada Resources, and Apache); and metals
(Inco and Titanium Metals). Also having a negative impact on the Fund's
performance were retailing (Sears, J.C. Penney, and May Department Stores);
telephones (GTE and AT&T); and real estate investment trusts (Developers
Diversified and Storage USA). Our view toward the former commodity-oriented
investments is that they continue to represent good values, particularly as the
current strength of the economy could eventually result in higher commodity
prices.

OUR STANDARDS

Given our previous comments regarding the overall stock market's strength, it
seems appropriate to present some guidelines we follow in managing the Fund. We
maintain these guidelines as qualitative parameters in selecting stocks and
managing the portfolio in general.

STICK TO THE STRATEGY:  One must have an investment strategy and adhere to it
in order to provide solid returns over the long term. We follow a value
strategy concurrent with the Fund's investment objective of capital growth
and current income. We will continue to do so.

BE PATIENT AND FOCUS ON THE LONG TERM: We focus on long-term returns; therefore,
the portfolio has relatively low turnover.

TRADE ONLY WHEN THERE IS A COMPELLING REASON: All trades have two cost
components -- commissions and execution costs. Although commissions are quite
low for the Fund, execution costs can be significant.

DON'T ACT ON EMOTION: Experience shows that emotional decisions are seldom
correct.

DON'T RELY ON MARKET TIMING: Experience has also shown that market timing does
not work over the long term. Historically, market timers are not successful in
every market cycle.

DON'T BASE DECISIONS ON ECONOMIC FORECASTS: As with market timing, history shows
that relying on economic forecasts can produce subpar returns. Economic
forecasts are unreliable and can lead to poor investment decisions.

GENERAL DISCUSSION

by Portfolio Managers David Peebles, Albert C. Sebastian, and 
W. Travis Selmier, II (Foreign Stocks) and R. David Ullom (Domestic Stocks)

MARKET CONDITIONS

While past performance is no guarantee of future results, the VA World Growth
Fund return of 22.42% has outperformed the Lipper Global Fund Index/1/ return of
20.55% for the 12-month-period ended June 30, 1997. The performance in most
emerging markets, Europe, and the United States has been favorable while the
Japanese equity market has continued to underperform.

INTERNATIONAL

Europe - Over the past six months, European markets provided favorable returns
which reflect accelerated earnings growth and further corporate restructuring.
We increased our exposure to stocks which benefit from stronger economic growth
as well as increased export opportunities due to a stronger U.S. dollar. Our
holdings in Spain, Portugal, the Netherlands, and Switzerland made significant
contributions to our European performance.

     Foreign investing is subject to additional risks such as currency
     fluctuations, market illiquidity, and political instability which are
     discussed in the prospectus. Since return on any investment is generally
     commensurate with risk, investors should be aware of the potential
     volatility associated with foreign markets.

INVESTMENT PROGRAM:

Not less than 65% of the Fund's assets are invested in a diversified portfolio 
of common stocks and other equity securities of both foreign and domestic 
issuers representing at least three countries, one of which may include the
United States. The remainder of the Fund's assets may be invested in marketable
debt securities having remaining maturities of less than one year which are
issued or guaranteed as to both principal and interest by the U.S. government or
by its agencies.

                 AN OVERVIEW (CONTINUED)        JUNE 30, 1997


Japan - Since our last report, some political stability has returned and
economic growth has picked up. However, continued problems in the banking
system, rising interest rates, and higher equity valuation levels vis-a-vis
other developed markets lead us to maintain an underweighted position. We
continue to hold large capitalization stocks with an emphasis on export-related
companies.

Emerging Markets - Emerging markets have shown some rebound since the beginning
of the year, with Latin American and East European markets showing stronger
performance than Asian markets. Economic recovery in Argentina and Mexico and
economic structural reform in Brazil continue to support those markets. While
concerns about the Asian growth story have caused worries, we continue to
believe that Asian growth prospects are still bright. Hong Kong, China, Taiwan,
and Indonesia have remained strong performers, while Thailand, the Philippines,
and Korea have suffered because of concerns over currency weaknesses.

UNITED STATES

Over the past six months, the domestic stock weighting in the Fund increased
only slightly from 23.7% as of December 31, 1996 to 24.1% as of June 30, 1997.
This increase does not reflect a change in our outlook toward U.S. equities.

During this reporting period, we slightly reduced our holdings in healthcare,
tobacco, and specialty retailing and eliminated our holdings in paper & forest
products. In turn, weightings were increased in electronics - semiconductors,
communication - equipment manufacturers, and bank holding companies. Given our
increased exposure to technology-related industries, we continue to believe that
the future will produce strong earnings growth for these companies.

                 AN OVERVIEW (CONTINUED)        JUNE 30, 1997


OUTLOOK

For the balance of 1997, we expect continuing economic improvement with
accelerating earnings growth in Europe. In the United States, we see slower
economic and earnings growth. Japan is still a market with selective
opportunities. The continuation of low inflation and good economic growth
provides a favorable backdrop for most emerging markets. The portfolio continues
to be overweighted in emerging markets, Europe and other developed markets at
the expense of Japan and the United States.

GENERAL DISCUSSION

THE MARKET

Common Stocks -- The Standard & Poor's 500 Index registered a gain of more
than 20% for the first six months of 1997, despite the fact that the Federal
Reserve raised interest rates.  Interest rates are still relatively low,
inflation appears to be in check, and overall corporate earnings have been
favorable - all factors that led to dynamic stock market performance in the
first half of 1997.

Debt Securities -- Over the past six months, interest rates have been quite
volatile.  Many credit this movement to investors changing their opinions
about the economy. In February, March, and April, interest rates rose sharply
as strong economic numbers caused investors to fear higher rates of
inflation.  However, since the end of April, interest rates have come down as
the economy showed signs of slowing, lessening the perceived need for the
Federal Reserve to raise overnight rates.


INVESTMENT PROGRAM:

Approximately 60% of the Fund's  assets are invested in equity securities
selected for total return potential and approximately 40% are invested in
debt securities of varying maturities. On June 30, 1997, the portfolio mix
was 63.2% common stocks and 36.1% fixed-income securities.

PORTFOLIO STRATEGIES

Common Stocks -- This portfolio holds blue chip common stocks which are
considered to be undervalued with regard to assets and/or earnings. The
portfolio is well diversified in 22 industries and 37 companies. The
industries with the highest percentage of assets are healthcare (diversified,
drugs, and medical products); oil (domestic and international); bank holding
companies (regional and money center); and telephones. The best performing
industries for the period were healthcare - diversified; medical products;
machinery -  diversified; insurance - property/casualty; telecommunications
(long distance); and office equipment.  The worst performing industries were
oils - domestic, aerospace/defense, and electrical equipment.

The following common stocks were up more than 30% during the period: Xerox,
Bristol-Myers Squibb, American Home Products, Bausch & Lomb, Caterpillar,
Deere, and Sprint.  Company stocks with negative returns included Pharmacia &
Upjohn, Unocal, GTE, and Rockwell International.

In the last six months, we added Chase Manhattan, Bausch & Lomb, SouthTrust, RJR
Nabisco, Ford, and Kimberly-Clark. We sold Nordstrom, J.C. Penney, Dow Chemical,
and American Brands.

Debt Securities -- As of the end of the reporting period, the bond segment had
a weighted average maturity of 7.1 years and a modified duration of five
years.  This represented very little change from the last reporting period.
We have kept these parameters steady because we are not relying on an
interest rate forecast.  No one has been successful in predicting the course
of interest rates over time.  Instead, we believe that our focus should be on
securities that have the potential to provide attractive levels of income and
total return. This philosophy has led us to invest primarily in mortgage
pass-throughs and BBB rated intermediate corporates, which has resulted in
lowering the Fund's volatility while providing higher income.

While past performance is no guarnantee for future results, the total return for
the bond portfolio was 4.17% for the last six months versus 3.09% for the Lehman
Aggregate Bond Index/1/. Contributing to the Fund's strong performance was the
larger percentage of corporates and mortgages versus treasuries in the portfolio
compared to the Index. In addition, positive developments at Kmart, Washington
Real Estate Investment Trust, and Great Atlantic & Pacific Tea resulted in
additional price appreciation for the overall portfolio.

OUTLOOK

Common Stocks -- For the next six months, it appears interest rates and
inflation will remain relatively stable and corporate earnings growth will be
good.  Stock market increases are expected to continue -- but returns are not
anticipated to be as good as the first six months.  A rise in interest rates
would cause a correction in the stock market. We will remain overweighted in
healthcare, banks, and telephones.


Debt Securities -- There is still a great deal of uncertainty whether the
economy will pick up or slow down during the remainder of the year. Given
this uncertainty, we will continue our focus of trying to find securities
that will provide attractive yields for the long-term investor.

COMPARISON OF FUND TO BENCHMARK


[GRAPH APPEARS HERE]


DATA REPRESENT THE LAST BUSINESS DAY OF EACH MONTH.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Aggressive Growth Fund to the broad-based Russell 2000 (R)
Index, a widely recognized small-cap index which most closely resembles the
holdings of this Fund. The Russell 2000 (R) Index is an unmanaged index
consisting of the 2,000 smallest companies within the Russell 3000 (R) Index.
The calculations for the Russel 2000 (R) are based on a starting date of May 1,
1997, whereas the calculations for the VA Aggressive Growth Fund are based on a
starting date of May 5, 1997. This comparison is for illustrative purposes only.

GENERAL DISCUSSION
by Portfolio Managers John K. Cabell and
Eric M. Efron

The Market

On May 5, 1997, we began purchasing stocks for the USAA Life VA Aggressive
Growth Fund. Since that date, investors have enjoyed robust returns from both
small and large capitalization stocks. While past performance is no guarantee of
future returns, during this less than two month period, the Russell 2000 (R)
Index for small capitalization stocks appreciated 9.36%, while the S&P 500
Index* grew 6.61%. The VA Aggressive Growth Fund returned 11.60% over the same
period. We attribute the Fund's performance to a rebound in small capitalization
stocks that occurred in the second quarter and a more robust Initial Public
Offering (IPO) market.

Portfolio Strategy

Since this is a new Fund, we think it is appropriate to devote this
commentary to a discussion of our investment objective, strategy, underlying
philosophy, and the characteristics we expect the Fund to manifest.

Our investment objective is long-term capital appreciation pure and simple --
nothing more, nothing less. Our strategy is to invest in companies that are
experiencing, or are expected to experience, rapid growth in sales and
earnings over a prolonged period. We believe profits are the ultimate
determinant of value. The more a company earns, the more it is worth. The
more rapidly a company's

Invests in Equity Securities. The Fund will invest in companies that have the
prospect of rapidly growing earnings.

earnings grow, the more rapidly the company's value will appreciate, and thus be
reflected in stock price appreciation.

We are growth, not value, investors. Our main concern is not whether a stock is
cheap relative to underlying assets but rather whether we believe a company in
which we invest is going to grow and become more profitable in the future.
Consequently, we are willing to pay premium valuations for the companies in
which we invest because we look for these premiums to be repaid generously as a
result of rapid value build-ups.

On a philosophical level, we believe that change is central to existence. It is
the only constant. Things never stay the same. This principle applies in nature,
in history and culture, and in the business world. In the business world, the
rate of change is especially rapid. In order to flourish, much less survive, in
a constantly and relentlessly evolving environment, companies must embrace
change and adapt rapidly. Otherwise they are doomed to a marginal existence at
best.

In selecting investment candidates, we identify long-term trends of profound
change in our economy and society.  Then we look for companies that are
likely to take early advantage of the trends.  Some of the broader themes in
which we invest are telecommunications and computing revolutions, the drive
for efficiency, changing lifestyles and demographics, and industrial
consolidation, to name a few. Our thematic approach leads us to a broadly
diversified investment portfolio spread over a wide range of industries
including major concentrations in technology, communications, healthcare,
financial and other services, and energy.

We feel that small-to-midsize companies are particularly well suited to cope
with change.  They tend to be less bureaucratic and tradition-bound than
their larger counterparts, and this puts them in a superior position to adapt
and be innovative.  We hasten to say, however, that aggressive growth, as we
perceive it, does not preclude investing in large capitalization stocks.  A
number of larger, dominant companies have remained nimble and flexible, and
we do not hesitate to invest in them.

           AN OVERVIEW (CONTINUED)                       JUNE 30, 1997

As of June 30, 1997, 34% of our investment positions were in companies with
market capitalizations in excess of $1 billion.

In our opinion, ground-floor investing is crucial to a successful track
record.  For the most part, well-known situations are already reflected in
stock prices. Undiscovered situations have potentially higher
investment returns. With this in mind, we participate actively in the IPO
market.

We believe our investments can lead to strong long-term returns. However,
these results will come at a cost and that cost is risk.  The stocks we
invest in are extremely volatile, particularly on a short-term basis, and
this is likely to be reflected in the overall performance of the portfolio.
The impact of volatility diminishes with the passage of time, but all
investors in this Fund should be willing and able to assume high levels of
risk.

OUTLOOK

We view the Fund as an exciting investment opportunity, and we face the
future with enthusiasm.  We are confident that we can generate strong
investment returns over the long term.  We caution, however, that there will
be bumps along the road and that at times, these bumps will occur when we
least expect them.  Obviously, this volatility injects a high degree of risk
into the Fund.  Over time, this risk has the potential to translate into
significant financial rewards for those investors who are able to live with
the volatility.

Selmier, II, and Albert C. Sebastian

MARKET CONDITIONS

The performance in most emerging markets and Europe has been favorable while
the Japanese equity market has continued to underperform.

Europe--The European markets provided favorable returns over the period
reflecting accelerated earnings growth and further corporate restructuring.
Our exposure to stocks has benefited from stronger economic growth as well as
increased export opportunities due to a stronger U.S. dollar. Our holdings in
Spain, Portugal, the Netherlands, and Switzerland made significant
contributions to our European performance.

Foreign investing is subject to additional risks such as currency fluctuations,
market illiquidity, and political instability which are discussed in the
prospectus. Since return on any investment is generally commensurate with risk,
investors should be aware of the potential volatility associated with foreign

             AN OVERVIEW (CONTINUED)                  JUNE 30, 1997


Japan -- Some political stability has returned to Japan and economic growth has
picked up. However, continued problems in the banking system, rising interest
rates and higher equity valuation levels vis-a-vis other developed markets lead
us to maintain an underweighted position. We continue to hold large
capitalization stocks with an emphasis on export-related companies.

Emerging Markets -- Emerging markets have shown some rebound since the beginning
of the year, with Latin American and East European markets showing stronger
performance than Asian markets. Economic recovery in Argentina and Mexico and
economic structural reform in Brazil continue to support those markets. While
concerns about the Asian growth story have caused worries, we continue to
believe that Asian growth prospects are still bright. Hong Kong, China, Taiwan,
and Indonesia have remained strong performers, while Thailand, the Philippines,
and Korea have suffered because of concerns over currency weakness.

OUTLOOK

For the balance of 1997, we expect continuing economic improvement with
accelerating earnings growth in Europe.  Japan is still a market with
selective opportunities. The continuation of low inflation and good economic
growth provides a favorable backdrop for most emerging markets. The portfolio
continues to be overweighted in emerging markets, Europe, and other developed
markets at the expense of Japan.

               NOTES TO PORTFOLIOS OF INVESTMENTS IN SECURITIES

                           JUNE 30, 1997 (UNAUDITED)


General Notes

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

The cost of securities for federal income tax purposes is approximately the
same as that reported in the financial statements.

The percentages shown represent the percentage of the investments to net
assets.

ADS/ADR - American Depositary Shares/ Receipts are foreign shares held by a
U.S. bank which issues a receipt evidencing ownership.  Dividends are paid in
U.S. dollars.

GDS/GDR - Global Depositary Shares/Receipts are foreign shares held by a
non-U.S. bank which issues a receipt evidencing ownership.  Dividends are
paid in U.S. dollars.


SPECIFIC NOTES

(a) Security is exempt from registration under the Securities Act of 1933 and
has been determined to be liquid by the Manager. Any resale of this security
may occur in an exempt transaction in the United States to a qualified
institutional buyer as defined by Rule 144A.

CRE          Credit Enhanced

CATEGORIES AND DEFINITIONS

The securities in USAA Life VA Money Market Fund are divided into two
categories- fixed rate instruments and variable rate demand notes.

FIXED RATE INSTRUMENTS - consist of corporate and government notes and
commercial paper.  The coupon rate is constant to maturity.

VARIABLE RATE DEMAND NOTES (VRDN) - provide the right, on any business day,
to sell the security at face value on either that day or in seven days.  The
interest rate is adjusted at the stipulated daily, weekly, or monthly
interval to a rate that reflects current market conditions.  The VRDN's
effective maturity is the date on which the underlying principal amount may
be recovered or the next rate adjustment date consistent with applicable
regulatory requirements.  Most VRDNs possess a credit enhancement.

CREDIT ENHANCEMENT - adds the financial strength of the provider of the
enhancement to support the issuer's ability to repay the principal when due.
The enhancement may be provided by either a high quality bank, insurance compa
ny, or other corporation, or a collateral trust.  Typically, the rating
agencies evaluate the security based upon the credit standing of the credit
enhancement, rather than the credit standing of the issuer.

                          USAA LIFE INVESTMENT TRUST

                         NOTES TO FINANCIAL STATEMENTS


                                                       JUNE 30, 1997 (Unaudited)

1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
USAA LIFE 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 Delaware business trust consisting of seven separate
funds. The USAA Life VA Aggressive Growth and International Funds commenced
operations May 1, 1997 with an initial investment from USAA Life Insurance
Company (USAA Life). USAA Life is a wholly owned subsidiary of United Services
Automobile Association (USAA), a large, diversified financial services
institution.

The investment objectives of the Funds are as follows:

USAA LIFE VA MONEY MARKET FUND:  Highest level of current income consistent
with preservation of capital and maintenance of liquidity.

USAA Life VA Income Fund:  Maximum current income without undue risk to
principal.

USAA LIFE VA GROWTH AND INCOME FUND:  Capital growth and current income.

USAA LIFE VA WORLD GROWTH FUND:  Long-term capital appreciation

USAA LIFE VA DIVERSIFIED ASSETS FUND:  Long-term capital growth, consistent
with preservation of capital and balanced by current income.

USAA LIFE VA AGGRESSIVE GROWTH FUND: Appreciation of capital.

USAA LIFE VA INTERNATIONAL FUND: Primary objective is capital appreciation.
Current income is a secondary objective.

Shares of the Funds currently are offered only to the Separate Account of USAA
Life Insurance Company (the Separate Account) to serve as the funding medium for
certain variable annuity contracts offered by USAA Life.

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.  Portfolio securities, except as otherwise noted, traded primarily on a
domestic securities exchange are valued at the last sales price on that
exchange. Portfolio securities traded primarily on foreign securities exchanges
are generally valued at the closing values of such securities on the exchange
where primarily traded. If no sale is reported, the latest bid price is
generally used depending upon local custom or regulation.

2.  Over-the-counter securities are priced at the last sales price or, if not
available, at the average of the bid and asked prices.

3.  Securities purchased with maturities of 60 days or less and, pursuant to
Rule 2a-7 of the Investment Company Act of 1940, as amended, all securities in
the USAA Life VA Money Market Fund are stated at amortized cost which
approximates market value.

4.  Other debt and government securities are valued each business day by a
pricing service (the Service) approved by the Funds' Board of Trustees. The
Service uses the mean between quoted bid and asked prices or the last sale price
to price securities when, in the Service's judgement, these prices are readily
available and are representative of the securities' market values. For many
securities, such prices are not readily available. The Service generally prices
these securities based on methods which include consideration of yields or
prices of securities of comparable quality, coupon, maturity, and type,
indications as to values from dealers in securities, and general market
conditions.

5.  Securities which cannot be valued by the methods set forth above, and all
other assets, are valued in good faith at fair value, using methods determined
by the investment advisor under the general supervision of the Board of
Trustees.

B.  FEDERAL TAXES 

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute
substantially all of their income to their shareholders, the Separate Account
and USAA Life. Therefore, no federal income or excise tax provision is required.
As a result of certain permanent differences between book and tax basis
accounting for investments in passive foreign investment companies,
reclassifications have been made on the statement of assets and liabilities of
the USAA Life VA World Growth Fund at December 31, 1996 to increase accumulated
undistributed net investment income by $47,807 and to decrease accumulated net
realized gain on investments by $47,807.

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. Dividend income, less foreign taxes, if
any, is recorded on the ex-dividend date. If the ex-dividend date has passed,
certain dividends from foreign securities are recorded upon notification.
Interest income is recorded on the accrual basis. Discounts and premiums on
short-term and long-term securities are amortized over the life of the
respective securities.

D.  FOREIGN CURRENCY TRANSLATIONS 

The assets of the USAA Life VA World Growth, Aggressive Growth, and
International Funds may be invested in the securities of foreign issuers. Since
the accounting records of the Funds are maintained in U.S. dollars, foreign
currency amounts are translated into U.S. dollars on the following basis:

B-62 SEMIANNUAL REPORT 1997
<PAGE>
 
                          USAA LIFE INVESTMENT TRUST

                         NOTES TO FINANCIAL STATEMENTS

                (CONTINUED)          JUNE 30, 1997 (UNAUDITED) 

1.  Market value of securities, other assets, and liabilities at the mean
between the bid and asked translation rates of such currencies against U.S.
dollars.

2.  Purchases and sales of securities, income, and expenses at the rate of
exchange obtained from an independent pricing service on the respective dates of
such transactions.

Net realized and unrealized foreign currency gains/losses occurring during the
holding period of investments are a component of realized gain/loss on
investments and unrealized appreciation/ depreciation on investments,
respectively.

Net realized foreign currency gains/losses arise from sales of foreign currency,
currency gains/losses realized between the trade and settlement dates on
security transactions, and the difference between amounts of dividends,
interest, and foreign withholding taxes recorded on the Funds' books and the
U.S. dollar equivalent of the amounts received. Net realized foreign currency
gains/losses have been reclassified from accumulated net realized gain/loss to
accumulated undistributed net investment income on the statement of assets and
liabilities as such amounts are treated as ordinary income/loss for tax
purposes. Net unrealized foreign currency exchange gains/ losses arise from
changes in the value of assets and liabilities other than investments in
securities resulting from changes in the exchange rate.

E.  USE OF ESTIMATES 

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
may affect the reported amounts in the financial statements.

2)  DISTRIBUTIONS
USAA LIFE VA MONEY MARKET FUND

Net investment income is accrued daily as dividends and distributed monthly
to its shareholder, the Separate Account.  All net investment income
available for distribution was distributed at June 30, 1997. Distributions of
realized gains from security transactions not offset by capital losses are
made annually or as otherwise required to avoid the payment of federal taxes.

USAA LIFE VA INCOME, USAA LIFE VA GROWTH AND INCOME, USAA LIFE VA WORLD
GROWTH, USAA LIFE VA DIVERSIFIED ASSETS, USAA LIFE VA AGGRESSIVE GROWTH, AND
USAA LIFE VA INTERNATIONAL FUNDS

Distributions of net investment income and realized gains from security
transactions not offset by capital losses are made to the shareholders, the
Separate Account and USAA Life, annually or as otherwise required to avoid
the payment of federal taxes. At December 31, 1996, the USAA Life VA Income
Fund had a capital loss carryover for federal income tax purposes of
approximately $480,000 which, if not offset by subsequent capital gains, will 
expire in 2004. It is unlikely that the Board of Trustees of the Fund will 
authorize a distribution of capital gains realized in the future until the 
capital loss carryover has been utilized or expires.

3) INVESTMENT TRANSACTIONS

Purchases and sales/maturities of securities, excluding short-term securities,
for the six-month period ended June 30, 1997 were as follows:

4)  FOREIGN CURRENCY CONTRACTS

A forward currency contract (currency contract) is a commitment to purchase or
sell a foreign currency at a specified date, at a negotiated price. The USAA
Life VA World Growth and International Funds currently enter into currency
contracts only in connection with the purchase or sale of a security denominated
in a foreign currency. These contracts allow the Funds to "lock in" the U.S.
dollar price of the security. Currency contracts are valued on a daily basis
using foreign currency exchange rates obtained from an independent pricing
service. Risks of entering into currency contracts include the potential
inability of the counterparty to meet the terms of the contract and the Funds
foregoing the opportunity for potential profit.
