Not quite as much 'overkill' as 100 rounds from the A-10's Gau-8, but, if you watch the film, you'll note there were not much identifiable remains left.
IMHO, our PsyOps guys should make up a DVD of clips like this -- and sell them in the same Iraq marketplacess where the terrorists sell the DVDs of their beheadings of helpless prisoners. The voiceover should say, "You are next."
I like your thinking. Unfortunately, last I heard, the DoD says its a violation of the Geneva conventions for the U.S. military to distribute images of death or grievous wounds to our enemies (except for certain legitimate internal purposes, like training).
I'm not sure of the details of this policy. I guess we intend to prosecute any the soldiers of any other country that broadcasts images of our prisoners or our dead, so they want to have the same standards apply to our troops.
