Its not a Storm Trooper, but it is Imperial (istic)

"-When in doubt, empty your magazine.
-Never share a foxhole with anyone braver than you are.
-Never forget that your weapon was made by the lowest bidder.
-If your attack is going really well, it's an ambush.
-No plan survives the first contact intact.
-All 5 second grenade fuses burn down in 3 seconds." Excerpt from Murphy's Laws
