Regarding this and comment in the TV thread. I was wondering if you have ever seen "Saving Private Ryan" the massive production from Stephen Spielberg? It's a wartime based drama of course and is widely regarded for its "about as near as you can get" battle scenes. These include the landings on Omaha beach, forward attack on a hillside machine gun post. sniper attack and the final culmination battle for the last bridge crossing of a river in a bombed out village. Spielberg used a raft of combat veterans as advisors while he still had access to them. Huge budget for the thousands of extras, ordnance and CGI and it shows. It's 20 years old now and still regarded as one of the most realistic war movies ever made.
Best seen at the cinema with big screen and sound but I have the DVD if you haven't seen it and would like to watch it.
