Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many ROK soldiers died in 1950-53?
Scholarly bands for ROK military dead are typically given in the low hundreds of thousands; civilian dead on the peninsula are a larger, still-debated range (see the Korean War page). Use ranges, not a single spectacle number.
What is Yulgok?
A Park Chung-hee-era force-modernisation and industrialisation effort to reduce dependence on grant aid and worn US types. It is policy history -- and it sits beside, not instead of, the 12.12 coup file.
What is the 1953 treaty?
The US-ROK Mutual Defense Treaty, signed 1 October 1953, in force 1954. A political object that structured the defensive frontier. Not a live basing guide.
Did the ROK fight in Vietnam?
Yes. A large expeditionary force under Chae Myung-shin and successors, 1960s-73, still argued in Korean politics (civilian harm, veterans' disease, alliance motives). Dated history, not a template.
Is this a current order of battle?
No. No unit list, no missile-site map, no combined-command diagram, no mobilisation how-to. Era-bounded defensive force-structure history only.
1950-53 ROK military dead in scholarly hundreds-of-thousands bands; civilian dead higher -- full ranges on the Korean War page. Vietnam ROK dead and later disease fights are a second ledger.
Conscription years are a peacetime social cost unique in this atlas's intensity-for-an-institution score.
Bands
Dated span (1948 founding; 1950-53 war; Yulgok modernisation; 1990s-2010s defence reform as later hinges)
Republic of Korea Armed Forces is taught as 1948 founding; 1950-53 war; Yulgok modernisation; 1990s-2010s defence reform as later hinges. 1946-48 and 2010s-20s are the usual poles.
Theatre (The Korean peninsula as a defensive fro.)
The Korean peninsula as a defensive frontier; Vietnam as a 1960s-70s expedition; later UN and Gulf-era deployments as footnotes is the geography of the ledger -- cities, seas, plants, or ministries as the file requires.
Invasion and collapse
1950-06-25: The near-end of the force.
Yulgok years
1974-79: Modernisation as industrial policy -- beside 12.12's 1979 shock.
Regions
The Korean peninsula as a defensive frontier
Core theatre of Republic of Korea Armed Forces (1948 founding; 1950-53 war; Yulgok modernisation; 1990s-2010s defence reform as later hinges). A founding, not yet a tested institution.
Founding and near-end
1946-53: Constabulary to armistice.
Yulgok industrial force
1974-90: Domestic types as a state project.
Exporter weather
After 2010s: K9/K2/KF-21 as news -- not a live list.
US / UK / AU / CA classrooms
English hours still treat the ROK force as a US appendix. Korean War veterans in those four countries remember 1950-53 allies, not Yulgok.
Korean comparative reader
Almost every family has a conscript story. 1948 founding, 1950 near-end, 1953 treaty, Yulgok, and 12.12 as a separate coup file.

Makers
Syngman Rhee
Syngman Rhee (President (1948-60)) is a named maker of the Republic of Korea Armed Forces story. The founding civilian name -- wartime politics, conscription, and a 1960 fall. A state-and-army file, not a battle captain.
Paik Sun-yup
Paik Sun-yup (ROK general) is a named maker of the Republic of Korea Armed Forces story. The English-readable ROK field name of 1950 -- First Division, then higher command. Use to correct a MacArthur-only still.
Chung Il-kwon
Chung Il-kwon (ROK general / later PM) is a named maker of the Republic of Korea Armed Forces story. Army chief in the war years and a long public career -- an institutional name, not a clean hero stencil.
Sohn Won-yil
Sohn Won-yil (ROKN founder) is a named maker of the Republic of Korea Armed Forces story. The navy's civic founding name -- a maritime half English Korea books skip.
Park Chung-hee
Park Chung-hee (General / president) is a named maker of the Republic of Korea Armed Forces story. 1961 seizure (a coup file) and Yulgok industrialisation (this page's policy hinge). Split the sentences. No method for 16 May.
Chae Myung-shin
Chae Myung-shin (ROK general) is a named maker of the Republic of Korea Armed Forces story. Commander of the Vietnam expeditionary force -- a dated, argued chapter of alliance and domestic politics.
US "forgotten war" talk must not shrink ROK numbers.
Veterans' policy (including 5.18 and Vietnam Agent Orange arguments) is part of the cost afterlife.
