Fan Casting Sergeant in Neil Blomkamp's Halo

A career Marine non-commissioned officer, tough, competent, and unflappable. He leads troops through the corridor barricade, the beach assault, and the Forerunner labyrinth, keeping his men alive through sheer professionalism. He respects Master Chief without fawning and follows orders without ego. His voice—gravelly, commanding, authentic—is the sound of the UNSC Marine Corps.
