Sentry Guns make an appearance in Call of Duty: Modern Warfare 3 Special Ops. They appear in the equipment armory in survival. They also appear in campaign mode, in the missions firewall and fatal extraction. Unlike its multiplayer variant, the Sentry Gun needs time to spin up, and always fires in bursts. They look identical to its Call of Duty: Modern Warfare 2 counterpart. The sentry guns in Fatal Extraction reward the player with 100 XP upon destruction.
