Unidentified master gunnery sergeant

"Huh! My ass! Well, you can forget about those adjustments to your A2 scope! And you're surely..."

- 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 at the Cairo Station, 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. Later, he was killed when Covenant forces invaded the station. Two Elites entered his armory and fired upon him, and he returned fire with a shotgun. He was soon annihilated by the pair of Elites as the Master Chief entered his armory to assist him. His dying words were "'Get The Hell Outta My Armory split lip.'"

Confusion Over Rank
There has been a great deal of confusion regarding this character's name and rank. In the level The Armory, 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). This also might just be a way of Johnson to say "master of the armory."

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 the last human to see Spartan 117's face as of yet. At the beginning of Halo 2, we see the Chief put on his helmet, indicating that his face is visible. Never once during the course of the game does he take off his helmet. The case is the same as in Halo 3, which takes place almost directly after the events of the prior game; he never takes off his helmet.
 * On the rare occasion, Halo 2 will glitch, and if you move fast enough, and kill the elites you can save the Master Gunnery Sergeant. Unfortunately, he does not move.
