Attaining the rank of chief master sergeant is the pinnacle of an Air Force or Space Force enlisted person's career. Some chief master sergeants manage the efforts of all enlisted personnel within their unit or major subsection while others run major staff functions at higher headquarters levels.

By federal law, no more than 1.25% of the Air Force enlisted force may hold the rank of chief master sergeant.
