(a) When it is not practicable to assign enlisted persons serving with the staff of a commander to an established activity for administration and discipline, the commander may designate an officer of the staff to act as the commanding officer of such persons and shall notify the Judge Advocate General and the Commandant of the Marine Corps, or the Chief of Naval Personnel, as appropriate, of such action.
(b) If the designating commander desires the commanding officer of staff enlisted personnel to possess authority to convene courts-martial, the commander should request the Judge Advocate General to obtain such authorization from the Secretary of the Navy.
