Rules of Combat (from David Crippen)

- 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, when you are ready for them, when you are 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 a trap.

- 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 no longer your friend.

- If it's stupid but works, it is not stupid.

- When in doubt, empty the magazine.

- Never share a foxhole with anyone braver than you.

- Anything you can 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 you were smart enough to think of a plan, stupid enough to try it, and lucky enough to live through it.

- Don't ever be the first; don't be the last; and don't ever volunteer to do anything.

- Five-second fuses only last three seconds.
