The Pentagon was considering developing a 'homosexual sex bomb' designed to make enemy troops gay, it has been revealed.
The bomb would release a chemical aphrodisiac that would get the soldiers frisky and make them irresistible to each other.
It was hoped their "distasteful but completely non-lethal" homosexual behaviour would hit moral in the barracks, the New Scientist reports.
The plan was just one of many ideas put forward by scientists looking at new kinds of fighting.
Another proposal suggested spraying enemy troops with a chemical that would make their breath smell.
The "severe and lasting halitosis" would allow American troops to work out who was a foreign fighter and who was a civilian once combat was over.
There were also plans to coat soldiers with chemicals that would attract angry wasps and rats.
Another idea suggested making the skin of soldiers hypersensitive to the sun.
The proposals, from the US Air Force Wright Laboratory in Dayton, Ohio, date from 1994.
The lab sought Pentagon funding for research into what it called "harassing, annoying and 'bad guy'-identifying chemicals".
The plans have been posted online by the Sunshine Project, an organisation that exposes research into chemical and biological weapons.
Spokesman Edward Hammond says it was not known if the proposed $7.5m, six-year research plan was ever pursued.
