In plain language, non-stockpile materiel includes bombs, projectiles and rockets containing chemical agent, chemical agent testing kits, buildings contaminated by chemical agents, and much more. Non-stockpile chemical weapons contain several types of toxic agents.
Nerve agents attack the central nervous system and are lethal in tiny doses.
Mustard agents can cause external and internal blistering, and can be lethal. Phosgene, a choking agent, can cause serious health problems but is not a lethal agent. Army historical records and documents provide much of the information about non-stockpile materiel locations. These documents are located at military installation archives, at the National Archives in Washington DC and in other government agency files. Even with the thousands of documents and reports available, a lot of information regarding military chemical weapons activities has been either lost or destroyed.
