Unidentified master gunnery sergeant

- Master Gunnery Sergeant

The unnamed Master Gunnery Sergeant in charge of Cairo Station's armory was a non-commissioned officer. He helped the Master Chief get used to his new Mark VI armor by testing his shields.

Biography
Shortly after the Master Chief arrived on Earth, the Master Gunnery Sergeant fitted him with the Mark VI armor that Maria-062 had tested earlier. The Master Gunnery Sergeant also briefed the Master Chief on the shields of the new armor. He was killed soon after when Covenant forces invaded the station. Two Elite Major Domos entered his armory and fired on him, and he returned fire with a shotgun. He was cut down by the Elites as the Master Chief entered his armory to assist him.

Confusion over rank
There has been a great deal of confusion regarding this character's name and rank. In The Armory (Level), he is referred to as "Master Guns" by Sergeant Major Johnson. Many interpreted this as him being a Master Sergeant with the last name "Guns". However, "Master Guns" is an informal address for a Master Gunnery Sergeant, and the character's name is not known. In articles he is often referred to as the unnamed Master Gunnery Sergeant; the Armory's Master Gunnery Sergeant; or "Master Guns" (only if a direct quote from the game).

Trivia

 * If the player waits underneath the Armory away from the stairs before entering it the Gunnery Sergeant is invincible. He will hold off the two Covenant Elites but he cannot kill them and will die as soon as the player enters the Armory. On Legendary, one can wait as he takes down the Elite's shield before going up and engaging them.
 * He was voiced by R. Lee Ermey in Halo 2, and has made no further appearances since his death. In the game, he was another of the several NPCs.
 * The name "Master Guns" may be a pun to the fact that he runs the armory.
