Gunnery Sergeant (UNSC)

Gunnery sergeant is the seventh enlisted rank in the UNSC Marine Corps, just above Staff Sergeant and below Master Sergeant, and is a staff Non-commissioned officer.

Gunnery sergeants are commonly referred to by the informal abbreviation "gunny." This nickname is usually regarded as a title of esteem and/or cameraderie, and is generally acceptable for use in all situations except formal and ceremonial ones. Use of the term by lower-ranking personnel, however, remains at the gunnery sergeant's discretion.
