Gunnery Sergeant

Gunnery Sergeant is the seventh enlisted rank in the Starfleet Marine Corps, just above Staff Sergeant and below Master Sergeant, and is a staff non-commissioned officer. They are assigned a pay grade of E-7 and the title may be abbreviated as GySgt.

Gunnery Sergeants are commonly referred to by the nickname "Gunny". This nickname is usually regarded as a title of esteem, 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.
