Full Metal Jacket (1987)

Continuity mistake: When Gomer Pyle is in the toilet with his rifle and after shooting the drill instructor, Pyle sits down on the fourth toilet seat from the back of the room. In the next shot where Pyle kills himself, he is sitting on the third toilet seat. You can see this already from the front shot of Pyle when he kills himself because there is a rise in the wall next to the third seat, which is visible through the whole scene. It is more obvious in the following shot where you can see the row of toilet seats and Pyle sitting dead on the third one. (00:43:00 - 00:43:35)

Gunnery Sergeant Hartman: How tall are you private?
Private: Sir, five foot nine, sir!
Gunnery Sergeant Hartman: Five foot nine, I didn't know they stacked shit that high!

Trivia: Many of the extras in the boot camp scenes were actually serving members in the British Territorial Army. They were chosen because it was assumed that they would be familiar with drill. However the English drill practices were so different from the American Marine corps practices that R. Lee Ermey himself had to re-train the British troops to march in Marine Fashion. Ermey said it was twice as much work trying to re-train them than it would have been just training raw recruits.

Question: Private Joker asks the gunner on the chopper about how he is able to shoot women and children, and the gunner replies by saying 'it's easy, you just don't lead them so much'. Does anyone know what that means?
