The Organization of the UNSC Military is the way in which the UNSC Navy and UNSC Marine Corps organize their fighting forces into manageable sizes of manpower for use in combat operations. Though there have been many UNSC military units named in the books and games, the exact specifications of the UNSC armed forces organization remains unclear.
