Template:Rank Infobox Corporal is the fourth enlisted rank in the UNSC Marine Corps and the fifth enlisted rank in the UNSC Army, and is the lowest rank of non-commissioned officer. It is equal in rank to Petty Officer Third Class in the UNSC Navy.
Promotion to Corporal traditionally confers a large jump in authority and responsibility compared to promotion from Private through Lance Corporal.
While both branches share the rank of Corporal, the UNSC Marine Corps rank is equivalent to the UNSC Army Specialist rank, one rank under an Army Corporal.
