The UNSC Marine Corps is a branch of the United Nations Space Command Defense Force under the Unified Ground Command, specialized in expeditionary warfare. Though semi-independent, it was typically subordinated under the Department of the Navy. The service was merged with the UNSC Army as a unified ground warfare component following the conclusion of the Human-Covenant War, due largely to cripplingly heavy casualties sustained by both branches over the course of conflict and the post-war shift from military footing to reconstruction.
