CNN reports that "The U.S. military rejected a 1994 proposal to develop an 'aphrodisiac' to spur homosexual activity among enemy troops but is hard at work on other less-than-lethal weapons." Other suggestions included "using chemicals that could be sprayed on enemy positions to attract stinging and biting bugs, rodents and larger animals" and "creating 'severe and lasting halitosis' to help sniff out fighters trying to blend with civilians."

So basically the taxpayers' money was used to fund research into creating flamboyant, pungent enemies... ;-)
