While he's renowned for his subtlety, Kubrick wasn't afraid to be very blatant with his themes when required. Such is the case in Full Metal Jacket, when the tyrannical drill instructor Sergeant Hartman (R Lee Ermy) tells the privates he is training that they have to give their rifles women's names and sleep with them. There's even a scene where they march around holding their weapons in one hand and their genitals in the other, chanting, "This is my rifle. This is my gun. This is for killing. This is fun."
