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.

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. Don't ever be the first, don't ever be the last and don't ever volunteer to do anything. Five second fuses only last three seconds. It is generally inadvisable to eject directly over the area you just bombed.
