American ingenuity is an incredible force, particularly on the battlefield.

Weapons such as the M16 rifle have been battle-tested and refined to near perfection. Some American weapons, such as the atomic bomb, have been so powerful they changed the world.

These weapons are trusted by the US military to defeat the enemy.
