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.
