In the South Korean armed forces, ranks fall into one of four categories: commissioned officer, warrant officer, non-commissioned officer, and junior enlisted (""Byeong""), in decreasing order of authority. Commissioned officer ranks are subdivided into general officers ("Jangseong"; 장성/將星), field-grade officers ("Yeonggwan"; 영관/領官), and company-grade officers ("Wigwan"; 위관/尉官). The ranks of all three branches (the Army, Navy, and Air Force) of the South Korean Armed Forces share the same titles in Hangul. Most ranks of South and North Korea are identical, with some exceptions such as the supreme North Korean ranks.
