Factual errors: School boys are shown firing a .303 Vickers machine gun, which had a range of 4,500 yards. An outdoor firing range would always have a slope of earth or sand behind the targets to stop dead all bullets fired down the range. Not only is there no such slope behind the boys targets, but we can see they're firing down into a valley full of buildings, well within the 4.5km (2.8mi) range of the gun, jeopardizing the lives of the villagers!
