I completely agree w/ Tom on this one ....
I think that you're getting the reaction that you're getting b/c you've taken an idea that NO ONE has thought of or done before .... and its very thought provoking at that. For me, at least, it stabs at the heart of the very evil that war provokes, and specifically those cold ARSE winters during WWII. Just the thought that these GIs are are already on edge, they're on patrol and the suddenly one of them sees the distinct round, unnatural shape of a helmet and its too late .... "but why am I not dead yet?", is what's going though his brain ... instead of a burst from that MG42. .... I could go on ... but that's the point. From your still scene, I'm able to tell myself a story every time I look at it.
Just think how many stories you've been able to "tell" w/ this one!?! .... Consider too that this scene of yours had a REALLY good chance of actually happening. Think of the memories it would have brought back.
I had a tire blow the other day (dang construction workers!) and I thought for a half second that I was dead .... damn IEDs. THAT's the kind emotion that this draws.
MUCHO KUDOS for Mr. Steve-0!!! Congrats brother! .... I have no doubt that FSM will pick this one up ... Congrats again.
