Worker-Peasant Red Guards
The Worker-Peasant Red Guards (WPRG; ), also translated as Workers and Peasants' Red Militia (WPRM), is a paramilitary force in North Korea. It is the largest civil defense force in North Korea. It is not only under State Affairs Commission (until 2016 National Defence Commission) and Ministry of Defence control, but is also attached to the Workers' Party of Korea under its Military Leadership Department. It is thus responsible to the Supreme Leader in his capacity as Supreme  Commander of the Armed Forces. The militia is organized on a provincial/City and town/village level, and structured on a brigade, battalion, company, and platoon basis. The militia maintains infantry small arms, with some mortars, field guns and anti-aircraft guns and even modernized older equipment such as multiple rocket launchers like the BM-13 and older Ural D-62 motorcycles, although some units are unarmed indicating status as logistics and medical units. Its strength is estimated at 5 million personnel. History
The organization was established In order to make up for the shortage of troops as the Chinese troops that participated in the Korean War withdrew in April 1958, North Korea disbanded the Self-Defense Forces, previously under the command of the Ministry of Social Security, and on 14 January, 1959 the organization was formally established with workers, farmers, intellectuals, and students joining it, and had a force of 500,000 people. At first, they were required to receive military training while working for a living, but in 1962, in accordance with the policy of arming the entire population, the organization was expanded to include men aged 18 to 45 and single women aged 18 to 35. In 1971, the applicable age for the Workers' and Peasants' Red Guards was extended to 50 years old, and all men and single women aged 17 to 60 who were not transferred to the prison guards were targeted for formation, and it continues to this day. They were also widely mobilized to help with reconstruction projects following the mass destruction that occurred during the Korean War. In September 1970, the North Korean government established the Red Youth Guards as a youth wing of the unit. The name ‘Worker-Peasant Red Guards’ first appeared at the military parade commemorating the 65th anniversary of the founding of the Party on October 10, 2010, and thereafter North Korea began calling it the ‘Worker-Peasant Red Guards’.
