Back at camp, the men resort to anything to pass the time and keep fear and grief at bay, including drunken brawls, a practical joke on the padre and an insect-fighting contest with an American unit that degenerates into a massive fist fight. Bill receives a thinly-disguised break-up letter from his girlfriend back home. Whilst on leave in Saigon, Bung catches a young scam artist who has just robbed a pair of US soldiers. They take the boy's stolen cash and team up with the Americans for a wild night with hookers, in which even Bill indulges.
