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).
