Unified Ground Command

The Unified Ground Command (UniCom) has control of all UNSC ground-based operations and is loosely modeled on the now-defunct United States Marin Corps. UniCom's role includes, but is not limited to, disaster relief, infantry operations, search and reconnaissance ops, and other "ground pounder" duties. Naval special warfare troops are an exception and are controlled by NavCom.

The basic unit of the ground force operation is the squad, consisting of twelve soldiers, or thereabouts. Ground forces are further grouped into platoons, companies, battalions, regiments, and divisions. The force numbers given in the descriptions below are ideals, rarely matched exactly int eh field. At the higher levels, these numbers include a significant amount of support personnel such as logistics and administration.
