Our lad (and new father! Congrats, and welcome Grace!) BlackFive has a video of a truck full of fellow contractors getting ambushed in Iraq, while part of an Army convoy. Short version: They punch the gas, and keep their position with the US Army Hummers they're convoying with.
It's worth watching to hear the voices. Once again, I feel justified in my pride at being a Southerner. The leader, and coolest head, has an accent I would place at the Northern Alabama/North Georgia border. Just the kind of fellow I'd want riding beside me, in a pinch.
