The Indonesian National Armed Forces (TNI) uses a simplified ranking system for the three branches of Indonesian Army, Indonesian Navy and Indonesian Air Force. Most of the ranks are similar with differences for the rank titles of the high-ranking officers. Exception exists, however, in the ranks of the service members of the Indonesian Marine Corps. While Indonesian Marine Corps is a branch of the Navy, the rank titles of the Marine Corps are the same as those of the Army, but it still uses the Navy's style insignia.
