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.
Although the rank of Basic Airman was renamed Airman Basic on 5 February 1959, the insignia did not change. The next series of changes to Air Force enlisted ranks did not occur for almost eight years. In January, 1967 the position of Chief Master Sergeant of the Air Force was created. This position gained its own special insignia, the Chief Master Sergeant chevrons with a wreath encircling the center star.
