Which rank corresponds with the insignia of 3 chevrons above one star above 4 rockers?

The insignia described features 3 chevrons above one star and 4 rockers, which aligns with the rank of Sergeant Major (SgtMaj). In the United States Marine Corps, the insignia for a Sergeant Major includes the three chevrons, which represent the non-commissioned officer rank, and the one star above indicates that they hold the position of Sergeant Major, which is a senior non-commissioned officer rank.

While the ranks of Sergeant Major of the Marine Corps and Master Gunnery Sergeant have similar elements in their insignias, they each represent different roles and levels of authority. The insignia for Sergeant Major of the Marine Corps, for instance, includes a unique eagle and globe emblem along with the chevrons, signifying the highest non-commissioned rank in the Corps. Master Gunnery Sergeant also has its own distinct insignia involving a different arrangement of chevrons and rockers, which differentiates it from the Sergeant Major insignia. The rank of Brigadier General is an officer rank and does not use chevrons or rockers, making it distinct from the other non-commissioned ranks
