Unidentified master gunnery sergeant
From Halopedia, the Halo wiki
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.[1] He was killed soon after by two Elites as Covenant forces invaded the station. He was wielding the only Shotgun in the level against them. He was voiced by R. Lee Ermy in Halo 2, and has made no further appearances since his death. In the game, he was another of the several NPCs in the game.
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.
