In 1996, two American soldiers who operated the most sophisticated chemical-detection equipment used in the 1991 Gulf War told the US Congress that chemical weapons were found in Kuwait during and after the war, contradicting repeated statements from the Defense Department. The soldiers who worked in a mobile chemical-detection laboratory known as a Fox vehicle testified that their reports of chemical detection were largely ignored or dismissed by their superiors.
The Pentagon has been hiding evidence of exposure to Iraqi chemical weapons during the 1991 Gulf War.
