New Scientist magazine reported in May that the Pentagon's cutting-edge research agency, DARPA, was considering a human-launching device that works like a cannon, to blast special-forces troops (and maybe firefighters and police officers) at just the right trajectory so that they land on hard-to-reach locations, such as rooftops.

Other recent pentagon projects involve chemical agents which reportedly would make enemy soldiers irresistably physically attractive to each other - which I'm assuming would take the form of an aerosol cloud of highly concentrated Viagra/Cialis to give them the desire together with a pheromene additive in order to affect their orientation. Presumably the ensuing confusion would affect their morale and make them less willing to fight. 

...Make love, not war.
