There is some wild stuff here: nondiscernible bioinoculators and 7.62mm projectiles with anthrax or botulinum toxin. (Not a good idea to section one those!)

President Nixon had ordered an end to all U.S. biological and chemical warfare on 25 November 1969 and ordered everthing destroyed, but the CIA and Ft. Detrick’s SOD kept a small quantity (11 grams) of saxitoxin (shellfish toxin), launchers, and lancejets, a.k.a. “poison darts” in storage, first at Ft. Detrick and later in Washington, D.C.
U.S. Patent 3,344, 711, which is available at freepatentsonline.com. MBA filed its patent application, number 437,345, on 23 February 1965 for the silenced pistol and ammunition. In 1966, Army personnel doing a routine review of classified patent applications saw reference to dogs in the application – one use of the device was to silence guard dogs – and declassified it. As a result, the patent itself was not classified and in fact was published in the Patent Office Gazette .
