The rank associated with the E-6 grade in the Marine Corps is Staff Sergeant. This rank comes after Sergeant (E-5) and is an important leadership position within the Marine Corps structure. Staff Sergeants typically take on greater responsibilities, such as supervising junior Marines and managing tasks, as well as serving as a bridge between enlisted personnel and higher-ranking officers.
