In the film when the try to get onto Omaha beach (i think its that depicted in the film) and one of the rangers has a round ping of his helmet, he takes his helmet off and pokes his finger through the hole thinking to himself that bullet had my name on it. 1 second later a second round blows his skull apart. In a live battle surely the last thing you do is take your helmet off? Another question, are field medics (not special operational team medics) supposed to carry a rifle or sidearm?
