In 1979, a secret unit was established by the US Army. Defying all known military practice - and indeed the laws of physics - they believed that a soldier could adopt a cloak of invisibility, pass cleanly through walls, and, perhaps most chillingly, kill goats just by staring at them. They were the First Earth Battalion. And they really weren`t joking. What`s more, they`re back and fighting the War on terror. So unbelievable it has to be true - this is the real-life account that inspired the film.
