UNSC Marine Corps

The United Nations Space Command Marine Corps is a branch of the UNSC Defense Force that is responsible for land-based military operations as well as the protection of Naval vessels and installations from attack.

A rugged and diverse assortment of well equipped and well trained men and women, one of the Marine Corps's most notable conflicts was fighting a losing war against the Covenant's highly superior technology and numbers.

Origins
The UN Marine Corps (predecessor of the UNSC Marine Corps) were one of the primary combat groups fielded by the UN in the Interplanetary War, and were the first military organization deployed offworld in 2163. After the United Nations claimed victory in 2164, it reorganized into the UNSC, thereby changing the UN Marine Corps to the UNSC Marine Corps. Later, the UNSC Marine Corps would be responsible for dealing with Insurrectionist uprisings among UNSC colonies star systems.

Human-Covenant War
During the course of the Human-Covenant War, the Marines played a central role in maintaining a defensive stand as well as assaulting several Covenant base of operations. The battles of Harvest, Arcadia, Sigma Octanus IV, and Earth saw fierce fighting between Marines and the Covenant Army.
