Murphy's Laws of Combat:

1. You are not a superman.
2. If it's stupid but works, it isn't stupid.

6. Never forget that your weapon were made by the lowest bidders.
7. If your attack is going really ok it's an ambush.
8. No plan survives the first contact intact.
9. All 5 seconds grenade fuses will burn down in 3 seconds.
10. Try to look unimportant because the enemy may be low on ammo.
11. If you're forward of your position the artillery will fall short.
12. The enemy diversion you are ignoring is the main attack.
13. The important things are always simple.
14. The simpel things are always hard.
15. The easy way is always mined.
16. If you're short of everything except enemies: you're in combat.
17. When you've secured an area, don't forget to tell the enemy.

25. Radios will fail as soon as you need fire support desperately.
26. Anything you do can get you shot - including doing nothing.

28. The only thing that's more accurate then incoming enemy fire is incoming friendly fire.
29. Make it tough for the enemy to get in and you can't get out.
