A lot of information and good thoughts. Following is the best comment I have ever read.
Murphy's Rules of Combat
Never share a foxhole with anyone braver than you.
If the enemy is in range, so are you.
Don't look conspicuous -- it draws fire.
There is always a way.
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.
Radios will fail as soon as you desperately need fire support.
If you can't remember, the claymore is pointed at you.
If your attack is going well, you have walked into an ambush.
When you are short of everything but enemy, you're in contact.
Don't draw fire. It irritates the people around you.
The only thing more accurate than incoming enemy fire is incoming friendly fire.
Incoming fire has the right of way.
When the pin is pulled, Mr. Grenade is not our friend.
When in doubt, empty the magazine.
Tracers work both ways.
Recoiless rifles ...aren't.
Suppressive fires ...won't.
Friendly fire ...isn't.
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.
The easy way is always mined.
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.
The enemy diversion you have been ignoring will be the main attack.
A "sucking chest wound" is nature's way of telling you to slow down.
When you have secured an area, don't forget to tell the enemy.
Never forget that your weapon is made by the lowest bidder.
No OPLAN ever survives the first contact.
A Purple Heart just proves that you were smart enough to think of a plan, stupid enough to try it, and lucky enough to survive.
If it's stupid but works, it isn't stupid.
