Granted, I'm an excellent shot.
And I have the back of a gorilla. But if YOU were to get shot, it would take me a while to figure out just HOW to get you to safety.
If you don't mind being drug on a tarp or propped up on a handcart, than I could probably have you out of danger in, oh, about 2 hours.
Not to mention I'm really cranky and I think they're trying to keep a few terrorists alive for interrogation.
That could prove problematic!
