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: Do you suck dick, private?
Pvt Pyle: Sir no sir!
Gunnery Sergeant Hartman: Bullshit! I bet you could suck a golf ball through a garden hose.

Trivia: While R. Lee Ermey has received high praise for his role as Gunnery Sergeant Hartman, Ermey himself stated that Hartman is an inept drill instructor because Hartman not only physically abuses the recruits, which is never allowed, but also because any drill instructor would have noticed that Pyle was having a mental breakdown.

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?
