OPORD - Close width and destroy the enemy...

Murphy's Laws of Combat

Friendly fire - isn't.
The important things are always simple; the simple are always hard.
The easy way is always mined.
Teamwork is essential; it gives the enemy other people to shoot at.
Don't look conspicuous; it draws fire. For this reason, it is not at all uncommon for aircraft carriers to be known as bomb magnets.
Never draw fire; it irritates everyone around you.
If you are short of everything but the enemy, you are in the combat zone.
When you have secured the area, make sure the enemy knows it too.
Incoming fire has the right of way.
