11th Marines: Nov. 5, 1998

Many veterans of the Gulf War have been experiencing a variety of physical symptoms, collectively called Gulf War illnesses. In response to veterans’ concerns, the Department of Defense (DOD) established a task force in June 1995, to investigate incidents and circumstances relating to possible causes. The Investigation and Analysis Directorate (IAD) of the Office of the Special Assistant for Gulf War Illnesses assumed responsibility for these investigations on Nov. 12, 1996, and has continued to investigate reports of chemical warfare agent incidents. IAD’s interim report is contained here.

As part of the effort to inform the public about the progress of this effort, DOD is publishing (on the Internet and elsewhere) accounts that may contribute to the discussion of possible causes of illnesses of Gulf War veterans, along with whatever documentary evidence or personal testimony was used in compiling the accounts. The narrative that follows is such an account.

C. Analysis of Related Issues: In the process of investigating 11th Marines alerts and incidents, investigators studied other relevant factors: 1) the unit’s chemical detection capability in a polluted environment; 2) medical evidence, and 3) any possible special characteristics of the 11th Marines that could affect NBC response.
