Platoon, The Wind that Shakes the Barley, We were Soldiers, Saving Private Ryan, Waterloo, Zulu, Black Hawk Down, Enemy at the Gates, Inglorious Basterds, Das Boot, Schindler's Lists and Downfall are my favourite war films. I know some are less combat based then others but I feel they still all fit under the category.
T.V series - Pacific, Band of Brothers and M*A*S*H, M*A*S*H is my favourite T.V show of all time.
