Chief Master Sergeant of the Air Force shoulder marks may be worn on the 50/50 acrylic wool sweater and the blue or white cardigan sweaters. It is a privilege the Air Force’s most senior enlisted member shares with other Noncommissioned Officers in the ranks E-7 to E-9, which are classified as Senior Noncommissioned Officers or SNCOs. The position of Chief Master Sergeant of the Air Force was established in 1967, ten years after the United States Marine Corps created an equivalent position called Sergeant Major of the Marine Corps to serve as an advisor to the highest levels of the Air Force command.
Since that time, the insignia for the position has undergone several changes since the original version was introduced; it was identical to the standard Chief Master Sergeant insignia except for the addition of a wreath around the star above the three “rockers.” In 1991, one rocker was removed and an additional chevron placed at the top of the insignia, and in 2004 the wreath-encircled star was replaced by the coat of arms of the United States between two stars.
