The position of master gunner (MG) is held by a warrant officer class one; however, the appointment is different to that of a regimental sergeant-major (RSM) and in units which have both appointments, an RSM and a MG, the RSM is the ‘senior’ warrant officer. An RSM’s duties and responsibilities, within barracks, are mainly related to matters of discipline, man-management, ceremonial and protocol; whilst those of a master gunner are generally in relation to technically gunnery and instructional matters.

Currently there are three master gunner positions within the Royal Regiment of Australian Artillery: the Regimental Master Gunner; the Master Gunner - School of Artillery; and each regiment has a master gunner (the senior warrant officer instructor (a WO1) at what was previously known as the School’s Gunnery Wing was the Wing Master Gunner, and there used to be a Master Gunner – Land Command Artillery).

The School’s senior officer, a lieutenant colonel, is both the Commanding Officer and the Chief Instructor (CO/CI); the RSM is responsible to the officer in his position as the CO and the Master Gunner is responsible to officer as the CI.
