This was reported on the BBC website, one not known for pranksterism (although the Beeb was had last month), so I'm guessing it's true.

Anyway, read on:

US military pondered love not war

The unconventional proposals were made by the US Air Force The US military investigated building a "gay bomb", which would make enemy soldiers "sexually irresistible" to each other, government papers say. Other weapons that never saw the light of day include one to make soldiers obvious by their bad breath. The US defence department considered various non-lethal chemicals meant to disrupt enemy discipline and morale. The 1994 plans were for a six-year project costing $7.5m, but they were never pursued. The US Air Force Wright Laboratory in Dayton, Ohio, sought Pentagon funding for research into what it called "harassing, annoying and 'bad guy'-identifying chemicals". The plans were obtained under the US Freedom of Information by the Sunshine Project, a group which monitors research into chemical and biological weapons. Here's the link for the Sunshine Project's home page. From there, you can link to the 'aphrodisiacs' document, which will open in a frame. Or you can try this direct link (it's a .pdf file).
