TheUnited States Forces Korea personnel wear the ranks and insignia used by other service personnel of theUnited States Armed Forces in the territories of the United States.

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

While the North Korean ranks are inspired by theSoviet ranks,^[1] the South Korean ranks are inspired by the United States.^[2]

North Korean insignia follow the Soviet pattern, while South Korean insignia follow a mix of American and British rank insignia traditions.
