The men who stare at goats / Jon Ronson.

Enhanced descriptions from Syndetics:

Now a major film, starring George Clooney, Ewan McGregor, and Jeff Bridges, this New York Times bestseller is a disturbing and often hilarious look at the U.S. military's long flirtation with the paranormal--and the psy-op soldiers that are still fighting the battle.

Bizarre military history: In 1979, a crack commando unit was established by the most gifted minds within the U.S. Army. Defying all known laws of physics and accepted military practice, they believed that a soldier could adopt the cloak of invisibility, pass cleanly through walls, and--perhaps most chillingly--kill goats just by staring at them. They were the First Earth Battalion, entrusted with defending America from all known adversaries. And they really weren't joking. What's more, they're back--and they're fighting the War on Terror.

An uproarious exploration of American military paranoia: With investigations ranging from the mysterious "Goat Lab," to Uri Geller's covert psychic work with the CIA, to the increasingly bizarre role played by a succession of U.S. presidents, this might just be the funniest, most unsettling book you will ever read--if only because it is all true and is still happening today.
