Case Narrative

11th Marines

Case Narratives are reports of what we know today about specific events that took place during the Gulf War of 1990 and 1991. This particular case narrative focuses on NBC alerts experienced by the 11th Marines, an artillery regiment supporting the 1st Marine Division. The narrative provides information on each alert and assesses the likelihood that Marines of this unit operated in areas where chemical warfare agent was present. This is an interim report, not a final report. We hope that you will read this and contact us with any information that would help us better understand the events reported here. With your help, we will be able to report more accurately on the events surrounding 11th Marines. Please contact my office to report any new information by calling:

Special Assistant for Gulf War Illnesses
Department of Defense


Last Update: October 30, 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 November 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.
