Gregory Schofield (Duke)
Sergeant Gregory Schofield, AKA Duke, is obsessed with two things - girls and games. He is the best friend of Destroyer and seems to be a big hit for the ladies & immediately develops a crush on Samantha Grimm. He claims that the closest thing he has to family is Destroyer. Duke stays with Sam in her lab for most of the following events, initially helping Sam and Dr. Jenna Willits keep an eye on Dr. Todd Carmack. Later while Sam dissects the Imp that killed Goat, Duke goes to retrieve an extra bonesaw for her, but is attacked by a mutant Carmack. Duke attempts to kill him but his rifle jams and Duke attempts to make it back into the lab through a nanowall. The Imp follows only to be trapped in the nanowall as Sam activates it. Sam and Duke also witness the resurrection and suicide of Goat, at which point Sam realizes the Imp is Carmack, and the other Imp she was dissecting is actually Dr. Steve Willits. Sam and Duke are also present when Sarge kills Carmack.
Duke later goes with Sarge and The Kid through the ark after a mutant Curtis Stahl while Reaper and Sam stay behind in the lab. While Duke is uneasy with shooting the bodies of the UAC personnel, perhaps because some may only be unconscious, he along with Sarge shoot them anyways. Duke eventually sets off on his own while Sarge and The Kid go elsewhere, and as a result finds Pinky hiding under a number of corpses. They head back the ark chamber where they find Sarge, Sam and Reaper. Pinky explains that he had attempted to stop the Hell Knight monster (Stahl) with an ST Grenade, but couldn't get it to work. Sarge fearing, Pinky may be infected, gives the notion of shooting Pinky, despite Sam affirming that he isn't infected. The Kid arrives though alerting the group to the existence of unharmed survivors. Sarge, believing them to be infected orders The Kid to kill them, but he denies and tells Sarge to "go to Hell". Sarge kills The Kid for insubordination which causes Duke, Reaper, and Pinky to train their weapons on Sarge. The Hell Knight appears and captures Pinky, and the marines attempt to follow. While trying to get through another nanowall, an Imp grabs up through a floor vent at Duke's ankles and drags him down, killing him.
Duke's weapon of choice is what appears to be a standard issue RRTS assault rifle (A G36 mocked up to look futuristic). Like all RRTS weapons, it has an ammo counting computer on it and an attached flashlight. When his rifle jams, Duke switches to a Hekler & Kotch USP pistol. In addition, Duke's death is similar to that of Private Hudson's death in the film Aliens.
Duke seems to enjoy playing older video games, perhaps a reference to the withstanding Doom community.
In the novel based on the movie, Duke explains that he and Destroyer knew each other growing up on the streets. The game he plays while preparing for leave is Space Invaders.
