Statistics published in Encyclopedia Britannica’s 2003 Almanac indicate that 325,000 Gulf War vets were receiving compensation for service-related disabilities in 2000. The almanac lists 580,400 combatants in the Persian Gulf War of 1990-91, yet only 467 U.S. personnel were actually wounded during the conflict. The 325,000 disabled Gulf War vets are equivalent to 56 percent of the number of military personnel “serving in the theater of operation.”
On 18 August 2004 the San Francisco Bay View published the version in the question, with the Britannica source omitted, the word "permanent" added, and making the 325,000 sound more associated with the 580,400 number.
According to the US department of veteran's affairs:
More than 650,000 Service members served in Operation Desert Shield and Desert Storm from August 2, 1990 to July 31, 1991. For VA benefits eligibility purposes, the Gulf War period is still in effect. This means that anyone who served on active duty from August 2, 1990, to present is considered a Gulf War Veteran. For example, the Veterans Pension benefit requires service during a wartime period. Therefore, any Veteran who served on active military service for any period from August 2, 1990, to the present meets the wartime service requirement. (Emphasis added.)
In any case, correct statistics are as follows taken from Gulf War Era Veterans Report: Pre-9/11 at page 56:
Out of 581,683 US military who participated in operation Desert Storm, as of FY2009:
9,441 were dead
165,113 were receiving some form of disability compensation.
