UNSC High Command

UNSC High Command (HIGHCOM) is the highest operational command of the United Nations Space Command and is ultimately in charge of all personnel, equipment, and facilities used by the UNSC Defense Force. It is sometimes colloquially referred to as "the Admiralty", which is a misnomer as its staff was composed of personnel from all branches, not just the Navy. HIGHCOM consists of less than twenty members that work very closely to plan missions, set objectives, to ensure that there is no disputes over resources or the command hierarchy amongst the lower echelons.

It is split into two commands; the Unified Ground Command, coordinating all UNSC ground forces, and the UNSC Naval Command, in charge of the Navy. It exercises local authority through regional CENTCOMs, which have responsibility over certain areas of space. HIGHCOM is responsible for establishing numerous mandates and directives for the Office of Naval Intelligence. However, most sections of ONI often mislead or lie to HIGHCOM, while NAVCOM is often blindsided by the organization.

Top-level officers from every branch form the UNSC Security Council of HIGHCOM. With headquarters at the planets Reach and Earth, HIGHCOM has directed the strategy for the actions of the UNSC since its very beginning, from combating rebel forces such as the Insurrectionists to the genocidal war waged by the Covenant. After the Fall of Reach, the headquarters was relocated to the HighCom Facility Bravo-6 in Sydney.
