Sergeant Schofield, known as "Duke," is obsessed with two things: girls and games. He is the best friend of fellow Marine Destroyer, and seems to be a big hit with the ladies. After arriving on the UAC's Martian base, Olduvai, he immediately develops a crush on Sam, sister of his friend John Grimm. During an outbreak of genetically infected humans, he is dragged into a vent and persumed dead. According to the novel, Sam still wonders whether Duke was alive or not.
