Colonel Quint: They've sent a replacement for you.
Sgt. Sam Troy: An Englishman?
Colonel Quint: Anything wrong with that?
Sgt. Sam Troy: Yes, sir. I don't know him. Colonel, we've got to be sure of each other, how the other man's going to react every minute.
Colonel Quint: The man you're getting was in this desert while you were still sweating out the draft. Meet Sergeant Moffitt.
Sgt. Jack Moffitt: [Describing the ever-changing sand dunes that buried the supply dump] You see, the desert is like a lady - puts on a new face every day.
Sgt. Jack Moffitt: Troy, I seem to upset you.
Sgt. Sam Troy: I'm not upset, doctor. Just careful. Knowing my guys keeps us alive. You I don't know from a croquet ball.
