The National Military Establishment is the formal name for the numerous branches of the Oceanian military and gendarmerie. It consists of the Army, the Navy, the Air Force, the Marine Corps, the Space Corps, the National Guard, and the Coast Guard, as well the reserve and auxiliary components of each force. The President of the Republic is the commander-in-chief of the Military, with subordinate authority delegated to the Secretary of Defense, the Attorney General, and the Chief of Staff for each force.
The Military draws its personnel from paid volunteer servicemembers; conscription was discontinued in 1966 and permanently abolished in 2004. Active forces comprise 521,000 members while there are 260,000 reserve members, as well as 219,000 guardsmen in the national military police force.
Oceania spends about 10 percent of its annual budget on defense, about even with the world average in terms of military expenditures as a percent of gross domestic product. The Republic has adopted a doctrine of power projection in recent years, but sequestered military spending significantly in 2020 in response to a change in leadership. Still, the Oceanian Military is widely regarded as a significant force with broad capabilities.
The President of the Republic is the commander-in-chief of the National Military Establishment. They are supported in command and control, as well as in the defense policy apparatus, by numerous advisors, including the National Security Council and the Joint Chiefs of Staff, as well as officials who oversee certain branches of the Military.
The Secretary of Defense directs the Department of Defense, under which falls the Army, the Navy, and the Air Force. Each of these three forces is led by its own Chief of Staff — the Chief of Staff of the Army, the Chief of Staff of the Navy, and the Chief of Staff of the Air Force. Subordinate to the Navy is the Marine Corps, led by Commandant of the Marine Corps. Subordinate to the Air Force is the Space Corps, led by the Commandant of the Space Corps.
The Attorney General, as the head of the Department of the Interior, oversees the National Guard and the Coast Guard, each of which performs federal policing duties in its respective jurisdiction. The National Guard is led by the Chief of Staff of the National Guard, and the Coast Guard is led by the Chief of Staff of the Coast Guard.
Chiefs of Staff are, by law, the highest ranking general of each force. Each force has numerous deputy chiefs of staff, overseeing departments within the service, and the Reserve Corps and Auxiliary Corps of the Army, Navy, and Air Force are each led by a Commandant.
All five Chiefs of Staff, as well as the Commandants of the Marine Corps and the Space Corps, are members of the Joint Chiefs of Staff, which advises the President on military strategy.
