Now who brings a camera to a war just to film it? I know if I were in the army, I wouldn't have my AK-47 in one hand and a camera in the other. :P
You've obviously never seen any of the damn footage we have of WWII.
We've got videos of dog fights, firefights, bombing runs, artillery bombardment, planes getting shot down, tanks getting blown up, etc.
It's actually quite surprising.
