Republic of Korea Armed Forces (1948): ROK armed forces with the state

A defining social fact of the ROK state 1979 military politics -- see korea-1979; not a method The Republic of Korea Armed Forces were organised with the 1948 state, out of a constabulary and a politics of occupation, and were nearly destroyed in the first weeks after 25 June 1950. Paik Sun-yup, Chung Il-kwon, and a thin officer corps fought a retreat to the Pusan (Busan) Perimeter, then a UN war that included Inchon (15 September 1950) as a US-led amphibious hinge. The 27 July 1953 armistice and the 1 October 1953 Mutual Defense Treaty (into force 1954) made a defensive frontier army under a US alliance -- the institutional fact this page exists to explain. It is not a live order of battle, not a combined-forces directory, and not a how-to for any arm.

English-language memory under-teaches the ROK as an institution and over-teaches it as a US appendix. Korean civic memory is the opposite risk: parade modernity that skips 12.12 (12 December 1979) and the army's political interventions. This atlas splits those files: korea-1979 for the coup, this page for defensive force structure, Hanwha for the works. Intensity is mid because 1950-53 was existential; scale is regional. No current ORBAT.

A frontier army that had to be rebuilt twice -- in 1950 and in industry The ROK military is a 1948 institution that survived 1950 by alliance, then spent Yulgok trying not to be only an alliance appendix -- a political history of a defensive force. Constabulary origins, June 1950 collapse, Pusan, Inchon, a Chinese intervention, and an armistice that was not a peace treaty. Paik and Chung are named because the English file still forgets ROK officers beside MacArthur.
