The United Nations Space Command Grand Colonial Army (UNSCA), known more commonly as the UNSC Army or colloquially as the Colonial Army, is a branch of the UNSC Defense Force. It is responsible for the majority of the United Nations Space Command's surface warfare activities.
Capable of tracing its roots back to hundreds of years before its official formation in 2164, the UNSC Army has consistently held the title of largest department within the entire UNSC, military or otherwise. By 2580, reports indicated the UNSC comprised eight million actively serving individuals plus an additional twenty-four million reservists.
