Sergeant Major Instructor Gunnery. With their instantly recognisable white hat they have the ability to scare both Gunner officers and soldiers alike. An excess of technical knowledges leads to quizzing (some may say annoying) the gun position with subjects no ones knows about, and the truth be told, cares about. However when it all goes pete tong they are the first person everyone silently cries help to. Not to be confused with the milkman due to appearence.
infantry officer: Why the fuck is there a milkman on the gun position?
