Gunnery Sergeant Hartman: You had best un-fuck yourself or I will unscrew your head and shit down your neck!
In the scene where the sniper is shot, You can see blood on her face (especially on her upper lip) when she falls down after being hit, but when she lies on the floor afterwards, there is no blood on her face anymore.
R. Lee Ermey actually wrote all of Gunny Hartman's dialog himself. Ermey was involved in a serious car accident right before shooting, so Kubrick invited Ermey to come stay at his house in England to recover. While recovering Ermey read the script over and over, and he remarked that the Drill Instructor's dialog that was in the script was obviously the work of a screenwriter with a cliche imagination who obviously had no idea what boot camp was really like. So Kubrick allowed Ermey to re-write all of the dialog himself.
