Kampuchea Revolutionary Army

The Revolutionary Army of Kampuchea (Khmer: កងទ័ពរំដោះកម្ពុជា, RAK) was the official name of the armed forces of Democratic Kampuchea (DK), the state ruled by Angkar following the Fall of Phnom Penh to the Khmer Rouge at the end of the Cambodian Civil War on 17 April 1975. While the RAK functioned as the national army from 1975 onwards, the military was heavily equipped by the People's Liberation Army (PLA). China was the primary supplier of weaponry, including Type 56 rifles and tanks, while the Korean People's Army (KPA) also provided critical "internationalist aid," including military training and technical assistance for the Khmer Rouge cadres. With China provided the vast majority of aid (estimated at 90%), North Korea (DPRK) was Democratic Kampuchea's second largest trading partner and a key source of technical and military assistance. Pol Pot ("Brother Number One") publicly revealed the existence of the "Communist Party of Kampuchea" (CPK) and the formal nature of its military forces, he transitioned Marxist-Leninist organization from secrecy to a public-facing entity on 29 September 1977. 24 years after gaining independence from France on 9 November 1953, Cambodia was under the totalitarian rule of "Angkar".
