What is the rank associated with the insignia of 3 chevrons above crossed rifles above 2 rockers?

The insignia consisting of 3 chevrons above crossed rifles and 2 rockers is specifically associated with the rank of Gunnery Sergeant (GySgt) in the United States Marine Corps. This rank is a technical leadership position that reflects a significant level of experience and expertise. The three chevrons represent the non-commissioned officer status, while the crossed rifles signify the infantry role, which is a key focus within the Marine Corps. The two rockers below the chevrons further indicate that this is a higher enlisted rank, specifically Gunnery Sergeant, as opposed to others which feature different combinations of chevrons and rockers.

In contrast, the other ranks present different insignia combinations that signify their respective positions within the enlisted structure. For example, the Master Sergeant (MSgt) features 3 chevrons and 1 rocker, while the Master Gunnery Sergeant (MGySgt) has 3 chevrons and 4 rockers, and the First Sergeant (1stSgt) showcases 3 chevrons and a diamond above the rockers. Each variation is designed to convey distinct responsibilities and levels of authority within the Marine Corps hierarchy.
