The Admiralty also controls the Earth Marine Corps, which comprise all ship-board Marine Regiments, several Independent Marine Regiments in each Quadrant, and one Special Forces Regiment (the Deep Space Force).
The General Staff controls the Imperial Army, which comprises the Ground Force Divisions, the Internal Security Divisions, the Mobile Assault Brigades and two Special Forces Regiments.
There are also two Guard Regiments, one subordinate directly to the First Citizen and the other to the Senate.
