I'm truly honored and humbled by my selection to the rank of Master Gunnery Sergeant this past week.
Master Gunnery Sergeant (MGySgt) is the ninth and highest enlisted rank (along with the grade-equivalent ranks of Sergeant Major and Sergeant Major of the Marine Corps) in the United States Marine Corps. Master Gunnery Sergeants are senior staff non-commissioned officers, and are assigned a pay grade of E-9.
Master Gunnery Sergeants are sometimes referred to by the nickname "Master Guns" or "Master Gunny."
The Master Gunnery Sergeant insignia consists of a bursting bomb (colloquially referred to as a "pineapple" due to the similarity of its appearance) centered vertically between three chevrons and four rockers.
One of the major differences between the two E-9 grades is that Master Gunnery Sergeants retain their MOS, while Sergeants Major are given a new MOS to reflect their general command focus. This reinforces the Master Gunnery Sergeant's role as a provider of military leadership, technical acumen, and mastery of their MOS.
