The General Staff Department carried out staff and operational functions for the PLA and had major responsibility for implementing military modernization plans. Headed by the chief of general staff, the department served as the headquarters for the ground forces and contained directorates for the three other armed services: Air Force, Navy, and Strategic Missile Force. The General Staff Department included functionally organized subdepartments for artillery, armored units, engineering, operations, training, intelligence, mobilization, surveying, communications, quartermaster services, and politics. Navy Headquarters controlled the North Sea Fleet, East Sea Fleet, and South Sea Fleet. Air Force Headquarters generally exercised control through the commanders of the seven military regions. Nuclear forces were directly subordinate to the General Staff Department. Conventional main, regional, and militia units were controlled administratively by the military region commanders, but the General Staff Department in Beijing could assume direct operational control of any main-force unit at will. Thus, broadly speaking, the General Staff Department exercised operational control of the main forces, and the military region commanders controlled the regional forces and, indirectly, the militia.
