An old buddy of mine who was a platoon leader in Vietnam used to say to his guys before they went out for the day "Keep you eyes and ears open, and watch where you put your feet."

Today's equivalent of that is "Keep your wits about you, and don't trust everyone."

I tend to think when things go wrong "Hard and fast, aim for the eye socket, good follow through - then get the f' outa there."
