When entering battle or confronting your enemy, it's essential to have a kick ass "war face"  -- an expression of rage, vengeance, and brute instincts. It is more than a menacing look, it is a release of powerful emotions to induce fear while also elevating one's senses to their maximum effect.

Here are the 11 best war faces in military movie history:

"Predator" -- Mac's face emptying a minigun after losing his best friend.
