A letter report issued by the General Accounting Office with an abstract that begins "During the 1990-1991 Persian Gulf War, health problems prevented the deployment of a significant number of Army reservists. To help correct this problem the Congress passed legislation that required reservists to undergo periodic physical and dental examinations. The National Defense Authorization Act for 2002 directed GAO to review the value and advisability of providing examinations. GAO also examined whether the Army is collecting and maintaining information on reservist health. GAO obtained expert opinion on the value of periodic examinations and visited seven Army reserve units to obtain information on the number of examinations that have been conducted."
