From 1952 thru 1975  the United States used 7120 men in chemical weapons experiments using stuff like mustard agents, Sarin, other nerve agents, they also used some of the same veterans in drug tests at Edgewood Arsenal using LSD, PCP, etc  in all 254 substances.  Pages 20-23 show the Cold War tests  http://www1.va.gov//vhi/doc s/CBR_www.pdf

This report published in March 2003 shows that 2098 of the men were dead in FY 2000   40%, and of the survivors 54% of them were disabled another 2200 men, for a total death and disability rate of 74.43%. The VA has failed to find these men and claim they can't "find" us until 2009, why? http://www.iom.edu//CMS/379 5/4913/5842.aspx
