The most dangerous thing in the world is a Second Lieutenant with a map and a compass. There is no such thing as an atheist in a foxhole. A grenade with a seven second fuse will always burn down in four seconds. Remember, a retreating enemy is probably just regrouping for a counter-attack. If at first you don't succeed, call in an air-strike.
Exceptions prove the rule, and destroy the battle plan.
Success occurs when no one is looking, failure occurs when the General is watching. The enemy never watches until you make a mistake. One enemy soldier is never enough, but two is entirely too many. Whenever you have plenty of ammo, you never miss. Whenever you are low on ammo, you can't hit the broad side of a barn.
