Chief Master Sergeant (last name) A chief master sergeant in the U.S. Air Force is the highest senior non-commissioned officer rank and directly above senior master sergeant. It is equivalent to the rank of sergeant major in the Army, master gunnery sergeant/sergeant major in the Marines, and master chief petty officer in the Navy/Coast Guard.
SMSgts normally operate at the operational level of leadership. Promotion to senior master sergeant is the most difficult enlisted promotion to attain in the Air Force. It is the first enlisted grade to which results of a central promotion board are the primary factor in selection for promotion. Usually, less than ten percent of eligible master sergeants are selected for promotion to senior master sergeant in most years.
