Murphys Law of Combat Operations:

1. Friendly fire - isn't.

2. Recoilless rifles - aren't. 

3. Suppressive fires - won't. 

4. You are not Superman; Marines and fighter pilots take note. 

5. A sucking chest wound is Nature's way of telling you to slow down. 

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

7. Try to look unimportant; the enemy may be low on ammo and not want to waste a bullet on you.

8. If at first you don't succeed, call in an air strike. 

9. If you are forward of your position, your artillery will fall short. 

10. Never share a foxhole with anyone braver than yourself.
