The one exception to the status of the CMSAF as the highest-ranking enlisted member of the Air Force, which has yet to occur, is when an Air Force chief is serving as the Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff.  In this instance, the SEAC would outrank the CMSAF.  The CMSAF is appointed by the Air Force Chief of Staff (AF/CC) and serves as the senior enlisted advisor to the Air Force Chief of Staff and the Secretary of the Air Force on all issues regarding the welfare, readiness, morale, and proper utilization and progress of the enlisted force.  While the CMSAF is a non-commissioned officer, the billet is protocol equivalent to a lieutenant general.
