In the United States Army, the SEA for a battalion or larger-sized unit is usually a Command Sergeant Major. For Marine battalions and larger, a sergeant major typically takes the role. Navy ships and other commands will usually have a command, fleet, or force master chief petty officer (known as the Chief of the Boat on a submarine), while an Air Force or Space Force command chief master sergeant serves at Wing, Delta, Numbered Air Force, Field Operating Agency (FOA), Major Command, Field Command or at "Joint," DoD Agency levels.
In the United States Army and the United States Marine Corps, the senior enlisted advisor at the company or battery level (or other unit at similar echelon) is a first sergeant. In the Air Force and Space Force, the senior enlisted member of units smaller than those listed above for command chief master sergeant is either a chief master sergeant or a senior master sergeant and may also include a separate first sergeant authorization. In the Air Force a first sergeant can be an E7, E8 or E9, depending on size and mission of the unit, and is a temporary, special duty assignment.
