What sources? Are you counting the one from this thread? No one is even sure who the guy is. Hardly a credible source. And I couldn't find the reference to Col Coleman in any of the letters from the Marine OpsO. In contrast, sources from Pres Bush to Gen Myers to Gen Sanchez have attributed the Fallujah Brigade to Gen Conway. It may not have been Conway's first choice, but I don't think a full frontal assault on Fallujah was any higher.
My mistake. The Colman quote is from a recent WSJ story , last paragraph.
If his first choice was forbidden, restarting the assault on Fallujah is the about the only thing I can imagine it being. That was reported by the lead foreign affairs reporter from USA today, and now this confirmation.
Once the first choice is removed, its no longer a Marine decision.
