Michael, one of the few angels that I remember mentioned in the Bible. He was designated the protector and defender of Israel. A powerful angel.
Off the subject, I heard a representative, Steve Buyer, use the same phrase attributed to Frank Wuterich at Haditha. When describing the firings/resignations for the snaffu over Walter Reed, Rep. Buyer mentioned it was a matter of "Shoot first, ask questions later", or something close. Buyer was a JAG in Desert Storm. Pretty common phrase; guess it depends on who uses it and when.
