Michael Yon: "I saw Prosser's M4 on the ground, Where did that come from?This is a reporter. Well, not just any reporter.

'Give me some ammo! Give me a magazine!' I yelled, and the young 2nd lieutenant handed over a full 30-round magazine. I jacked it in, released the bolt and hit the forward assist. I had only one magazine, so checked that the selector was on semi-automatic."
