Halitosis bomb

The "Halitosis bomb" and "Gay bomb" are informal names for two theoretical non-lethal chemical weapons, which a United States Air Force research laboratory speculated about producing.

In 1994 the Wright Laboratory in Ohio, a predecessor to today's United States Air Force Research Laboratory, produced a three-page proposal on a variety of possible nonlethal chemical weapons, which was later obtained - complete with marginal jottings and typos - by the Sunshine Project through a Freedom of Information Act request.

In both of the documents, the possibility was canvassed that a strong aphrodisiac could be dropped on enemy troops, ideally one which would also cause "homosexual behavior". The documents described the aphrodisiac weapon as "distasteful but completely non-lethal". The "New Discoveries Needed" section of one of the documents implicitly acknowledges that no such chemicals are actually known. The reports also include many other off-beat ideas, such as spraying enemy troops with bee pheromones and then hiding numerous beehives in the combat area, and a chemical weapon that would give the enemy bad breath.
