- “We lost Checkman in the atmosphere.”— Dutch telling O'Brien about his death.
Checkman was an Orbital Drop Shock Trooper of the UNSC Marine Corps. He was assigned to MSgt Cortez' team aboard the UNSC Kronstadt as well as Dutch and O'Brien. He, along with his fellow squadmates were given the task of assassinating a Prophet on a Covenant-held world. Just like the rest of the squad, he was furious that a Spartan got ordered to lead the mission.
- Checkman is considered to be a "redshirt" character, as he is created merely to be killed.
