Defense Counterintelligence Command

The Defense Counterintelligence Command (DCC; Korean: 국군방첩사령부) was the military intelligence security agency of the Republic of Korea (South Korea) Ministry of National Defense (MND) tasked with advancing military counterintelligence through collecting and analyzing intelligence from around the world. It was founded as the Army Counter Intelligence Corps (commonly known as CIC or KACIC; meaning: Special Operation Forces) on 21 October 1950. The DCC was primarily responsible for analysis and development of intelligence collection and counterintelligence systems to create military security networks, clandestine and covert operations, countering hybrid threats, counterterrorism, defense (arms) industry security, executive protection, foreign military threat assessment to national security, forensic science for investigations, information warfare, military counterintelligence, military cybersecurity, psychological warfare, protect classified military information and documents, and support the investigation and interrogation of military crimes. The unit was reorganized into the Defense Counterintelligence Command on 1 November 2022. On 31 July 2026, the Defense Counterintelligence Command (DCC) was formally dissolved by the Ministry of National Defense after 49 years of operation, following years of controversy and allegations of misuse, most notably during the December 2024 martial law crisis.
