Comparative military ranks of Korea

Comparative military ranks of Korea refer to the ranks and insignia maintained by the three primary military powers present on the Korean Peninsula, those being the Republic of Korea Armed Forces (South Korea), the Korean People's Army of the Democratic People's Republic of Korea (North Korea), and the military forces of the United States in Korea.

In the South Korean armed forces, ranks fall into one of four categories: commissioned officer, warrant officer, non-commissioned officer, and enlisted, in decreasing order of authority. Commissioned officer ranks are subdivided into "Janggwan"-level (general) officers, "Yeonggwan"-level (field-grade) officers, and "Wi-gwan"-level (company-grade) officers. 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.

The following table lists the comparative ranks of the militaries in Korea, including their rank titles and insignia. In this table, the North Korean military rank insignia shown is that of their Army field uniform shoulder boards; their parade uniforms and uniforms of other branches use alternative color schemes with the same basic design. The South Korean and US militaries likewise have subdued versions of their insignia in each of their branches.

(Note on romanization: In the article, all South Korean ranks are spelled accordingly with the Revised Romanization of Korean system; all North Korean ranks use the McCune-Reischauer system.)

Officer Ranks

The shoulder boards and sleeve stripes of the US and ROK ranks applies only to their navies. Neither Marine Corps of the two nations maintain a five star General rank. The North Korean military does not maintain a separate Marine Corps as part of their armed forces, although it does maintain two Amphibious Sniper Brigades as part of their Special Forces.

Warrant Officer Ranks

All branches of the South Korean armed forces maintain a single Warrant Officer rank known as Junwi. Warrant Officers fall in between non-commissioned and commissioned officers.

The rank is denoted by a gold-colored Sowi insignia and, in the case of the ROK Navy, a single broken sleeve stripe. A Junwi may be considered to be a close equivalent to a Chief Warrant Officer in the United States armed forces.

The North Korean military and the US Air Force do not maintain any equivalent Warrant Officer positions.

Enlisted Ranks

Both Korean militaries share the same rank structure among all its branches. They also have enlisted ranks called "Corporal" and "Sergeant" in English, but are not considered non-commissioned officer ranks, though they are treated as one if they hold an NCO position.
