A member of the “Old Corps,” part of the Marines since World War I in France, Sergeant Haney is an inspirational model to young Marines such as Sledge. Although characterized by idiosyncrasies such as cleaning his rifle three times per day, talking to himself, and spending most of his time on his own instead of having a buddy, Haney is a stern, deeply experienced officer, committed to respecting the rules. On Pavuvu and Peleliu, during training as well as in battle, he ensures strict discipline, encouraging everyone to respect safety regulations. Although young Marines joke about Haney having gone “Asiatic,” they love and admire him deeply, respecting his authority as an esteemed fighter.
