Sledge’s section leader on Peleliu and 81 mm mortar platoon leader on Okinawa, Duke is a kind, fair, and generous man. He reassures Sledge when he sees him crying out of despair on Peleliu, thus proving both compassionate and intelligent in his capacity to help a soldier overcome traumatic emotions. On Okinawa, he demonstrates his ability to understand military logic beyond abstract rules, allowing Sledge to build a foxhole a few feet away from a dead Japanese corpse, instead of forcing him to dig at the exact spot planned by superiors. In addition, Duke is dedicated to showing respect to his men when he goes out of his way to explain the strategic importance of the fight of Shuri, Okinawa. This reveals his intellectual generosity and humility, as he shares information with them that is usually concealed from mere infantrymen.
