roster. Ranks 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 "Jangseong"-level (general) officers, "Yeonggwan"-level (field-grade) officers, and "Wigwan"-level (company-grade) officers. All three branches of the South Korean Armed Forces share the same rank insignia and titles in Korean (The English titles are given as comparative examples with the US Army ranks.). ROK Navy commissioned officer ranks have two distinct sets of rank insignia: On dress uniform, a series of stripes similar to Commonwealth naval ranks are worn; on service uniforms, working uniforms, and special uniform situations (combat utilities and flight suits), the rank insignia are the same as the equivalent rank in the Army or the Air Force. Commissioned officer ranks Warrant officer ranks Other ranks Budget South Korea has one of the highest defense budgets in the world, ranking 9th globally in 2020, with a budget of nearly $44 billion U.S. dollars. Overseas deployments As part of its mission, the ROK Armed Forces have engaged in peacekeeping operations, humanitarian, and disaster-relief efforts worldwide. In 2008, officers and soldiers of Unit Dongmyeong, stationed in Lebanon with the UNIFIL, received honorary medals from the United Nations.
