Rules of combat...

• If the enemy is in range, so are you.

• Incoming fire has the right of way.

• Don't look conspicuous: it draws fire.

• The easy way is always mined.

•  Try to look unimportant, they may be low on ammo.

• Professionals are predictable, it's the amateurs that are dangerous.

• The enemy invariably attacks on one of two occasions:         1. When you're ready for them.         2. When you're not ready for them.

• Teamwork is essential; it gives the enemy someone else to shoot  at.

• If you can't remember, the claymore is pointed at you.

• If your attack is going well, you have walked into an ambush.

• Don't draw fire, it irritates the people around you.

• The only thing more accurate than incoming enemy fire is incoming friendly fire.

• When the pin is pulled, Mr. Grenade is not our friend.

• If it's stupid but works, it isn't stupid.

• When in doubt empty the magazine.

• Never share a fox hole with anyone braver than you.

• Anything you do can get you shot. Including doing nothing. 

• Make it too tough for the enemy to get in and you can't get out.

• Mines are equal opportunity weapons.

• A Purple Heart just proves that were you smart enough to think of  a plan, stupid enough to try it, and lucky enough to survive.

• Don't ever be the first, don't ever be the last and don't ever volunteer to do anything.

• The quartermaster has only two sizes: too large and too small.

• Five second fuses only last three seconds.

• It is generally inadvisable to eject directly over the area you just bombed.
