Force fingerprint

The national security structure sized by active headcount, always from the head of state: row 1 the head of state and government, row 2 the governing bodies (grey, each as wide as the forces beneath it), row 3 the services and agencies coloured by security domain, row 4 the major commands, row 5 the major formations. A hatched segment is a body whose headcount is not published.

Order of battle

The whole national security structure from the head of state down to major formations. Bars are as wide as their headcount; the state and government bodies are drawn grey, as the government directory has them. Click a bar to zoom into it.

Known unknowns

  • The National Intelligence Service does not publish its headcount, budget breakdown or internal organisation; its staff numbers are classified by law.
  • The Defense Counterintelligence Command was dissolved on 3 August 2026 and its duties split between a new Defense Counterintelligence Headquarters, a Defense Security Support Group and a Security Investigation Group; the successors' strength and final official English names have not been published.
  • The Defense Intelligence Agency's subordinate signals intelligence unit (777 Command) and the strength of the Korea Defense Intelligence Command are not published.
  • The Republic of Korea Air Force's numbered combat commands are not described on an official English-language page and are omitted.

Equipment fingerprint

Holdings by taxonomy: row 1 the ministry and its services, row 2 the six domains, row 3 the categories, row 4 each platform held as wide as its count, row 5 its split into active, reserve and on order. A hatched segment is a platform held with no published count.

Holdings

One row per platform held. Each figure is a claim with a source: the most recent official figure where one is published, else the most recent Wikipedia equipment list, else SIPRI's delivered total. Figures are never averaged.
