Korean People's Army

• 1. Introduction

  ›

  The Korean People's Army stands today as the second largest military organisation in the world, an institution whose origins stretch back not to the country that commands it, but to a school near the Chinese city of Yan'an in 1939. From that remote wartime training ground, a force took shape that would fight the United States to a standstill, deploy secretly into Russian uniforms in 2024, and accumulate a nuclear arsenal that analysts estimate at between twenty and sixty warheads. What kind of military operates its own factories, farms, and trading arms? What does it mean for a constitution to declare that the armed forces exist to "defend unto death the Party Central Committee headed by the great Comrade Kim Jong Un"? And how did a military born under Soviet tutelage transform itself, decade by decade, into something answering to no outside power at all?

• 2. Born in Yan'an

  Kim Tu-bong and Mu Chong were the two men who founded the Korean Volunteer Army in Yan'an, China, in 1939, alongside a school designed to prepare military and political leaders for a Korea not yet free. By 1945 the force had grown to roughly 1,000 men, most of them Koreans who had deserted from the Imperial Japanese Army. Fighting alongside the Chinese communist Northeast Anti-Japanese United Army, the KVA drew its weapons and ammunition directly from that alliance. After Japan's defeat, the KVA moved with the Chinese Communist Party into eastern Jilin, recruiting from the large ethnic Korean communities around Yanbian before pushing on into Korea itself.

  The Soviet side of the story began almost immediately after World War II ended. The Soviet 25th Army headquarters in Pyongyang issued an order on the 12th of October 1945 dissolving all armed resistance groups in northern Korea. Two thousand Koreans who had previously served in the Soviet Red Army were then dispersed across the country to build new constabulary forces, and that force was formally created on the 21st of October 1945.

  From those parallel threads, a national army was woven. A railway security unit was announced on the 11th of January 1946 and activated on the 15th of August of that year. Military academies followed: the Pyongyang Academy, which became No. 2 KPA Officers School in January 1949, and the Central Constabulary Academy, which became the KPA Military Academy in December 1948. The formal announcement of the Korean People's Army came on the 8th of February 1948, the day after the Fourth Plenary Session of the People's Assembly approved splitting the roles of the military and the police. That date preceded the proclamation of the Democratic People's Republic of Korea itself by seven months.

  Joseph Stalin personally equipped the KPA with modern armaments before the Korean War began, a decision whose consequences would arrive quickly. In the opening months of 1950, KPA forces drove South Korean units southward and captured Seoul. Then came the U.S. amphibious landings at the Battle of Incheon and a subsequent push toward the Yalu River. That counteroffensive destroyed an army: seventy thousand of the KPA's one hundred thousand troops were lost in the autumn of 1950.

  China's open military intervention, staged on the 4th of November of that year, altered the war's dynamics entirely. For the remainder of the conflict, the KPA played a secondary role to the Chinese People's Volunteer Army. By the time the Armistice was signed in 1953, the KPA had suffered 290,000 casualties and lost 90,000 men as prisoners of war.

  The Armistice brought the Military Armistice Commission into existence to oversee the agreement's terms. The Neutral Nations Supervisory Commission, composed of delegations from Czechoslovakia, Poland, Sweden, and Switzerland, carried out inspections to verify that no new reinforcements or weapons entered Korea. That ceasefire structure has governed the Korean Demilitarized Zone ever since, and the KPA still identifies the Republic of Korea Armed Forces and United States Forces Korea as its primary adversaries across that line.

• 4. Power and the Party

  ›

  Since 1990, the KPA's internal command structure has changed repeatedly, and most of the details remain unknown outside North Korea. What is documented begins with the deaths of the aging leadership: Kim Il Sung died in July 1994, Minister of People's Armed Forces O Jin-u died in February 1995, and Minister of Defence Choe Kwang died in February 1997. Each death created space for Kim Jong Il to reshape the institution around his own authority.

  On the 24th of December 1991, Kim Jong Il was appointed Supreme Commander of the Korean People's Army. Four months later, on the 20th of April 1992, he received the rank of Marshal, while his father was simultaneously elevated to Grand Marshal. In April 1997, on the 85th anniversary of Kim Il Sung's birthday, Kim Jong Il promoted 127 general and admiral grade officers. The following April he ordered the promotions of 22 more.

  Between December 1991 and December 1995, nearly 800 of approximately 1,200 high-ranking KPA officers received promotions or preferential assignments. Political officers drawn from the party monitored the daily lives of generals in a manner analysts compared to Soviet political commissars. The KPA's General Political Bureau held equal status to the WPK Central Committee itself during this era.

  Kim Jong Un reversed that balance. The Supreme People's Assembly amended the constitution in June 2016, abolishing the National Defence Commission and replacing it with the State Affairs Commission, a body with more civilian members than its predecessor. Kim became its chairman on the 29th of June 2016. At the 8th WPK Congress in 2021, the number of military delegates fell from 719 at the previous congress to 408. The phrase "military-first policy" was removed from the party charter and replaced with "people-first politics". Kim addressed the KPA not as the "army of the leader" but as the "army of the party", a phrasing that moved North Korea's civil-military relationship closer to the model found in other socialist states.

• 5. The Founding Date Dispute

  ›

  Until 1977, the official founding date of the Korean People's Army was the 8th of February 1948, the date of the formal announcement. Then North Korean historiography introduced a competing claim: that Kim Il Sung had personally established the Korean People's Revolutionary Army on the 25th of April 1932, in Ando County, Manchuria, as an anti-Japanese guerrilla unit. In 1978, April 25 was designated as the "Anniversary of the Founding of the People's Army", and large-scale commemorative events were held across the country.

  From 1978 to 2014, only the 1932 anniversary was actively celebrated. Decennial anniversaries of both dates were treated as major events, though the earlier date carried more official weight during that period. By 2019, however, the founding date had reverted to the 8th of February 1948. The shift back and forth is a window into how North Korean leadership has used military history as a political instrument, anchoring legitimacy to Kim Il Sung's guerrilla origins when that narrative served the moment.

• 6. Reach Beyond Korea

  ›

  Up to 200 Korean People's Air Force pilots flew combat missions during the Vietnam War, scoring kills against U.S. aircraft. Two KPA anti-aircraft artillery regiments were deployed to North Vietnam as well. During the Libyan-Egyptian War and the Angolan Civil War, North Korean troops allegedly saw combat. North Korean instructors trained Hezbollah fighters in guerrilla warfare tactics around 2004, before the Second Lebanon War. During the Syrian Civil War, Arabic-speaking KPA officers may have helped the Syrian Arab Army plan operations and supervised artillery bombardments in the Battle of Aleppo.

  In total, more than 5,000 foreign personnel have been trained inside North Korea, and over 7,000 military advisers have been dispatched to some forty-seven countries. Organisations that received North Korean assistance include the Polisario Front, the Janatha Vimukthi Peramuna, the Communist Party of Thailand, the Palestine Liberation Organization, the Islamic Revolutionary Guard Corps, and Zimbabwe's Fifth Brigade, which received its initial training from KPA instructors.

  The United Nations named the Korea Mining and Development Trading Corporation, known as KOMID, in April 2009 as North Korea's primary arms dealer and main exporter of equipment related to ballistic missiles and conventional weapons. Korea Ryonbong was also named as a supporter of military-related sales. In the fall of 2024, roughly 10,000 KPA troops, including Special Operations Forces, were sent clandestinely to Russia to fight alongside Russian forces in the Kursk offensive. They operated in Russian uniforms under Russian command. Initially denied by both governments, the deployment was acknowledged after Russia announced that the last Ukrainian forces had been pushed out of Kursk Oblast.

• 7. Nuclear and Asymmetric Arsenal

  ›

  On the 9th of October 2006, North Korea announced its first nuclear test. The United States Geological Survey and Japanese seismological authorities detected a preliminary magnitude 4.3 earthquake from the test site, confirming the claim. A second test was claimed in 2009. On the 3rd of September 2017, the North Korean leadership announced a hydrogen bomb detonation at the Punggye-ri nuclear test site in North Hamgyong Province at 12:00 pm local time. South Korean officials estimated the yield at 50 kilotons, with many international observers assessing the test as likely thermonuclear.

  Also in July 2017, North Korea conducted two tests of an intercontinental ballistic missile capable of carrying a large nuclear warhead. The Pentagon confirmed both tests, and analysts estimated the missile's potential range at 10,400 km, enough to reach mainland U.S. territory on a flatter trajectory. Estimates of the total nuclear stockpile vary widely: Hans M. Kristensen and Matt Korda placed the figure at between twenty and thirty assembled weapons, while U.S. intelligence has placed it at between thirty and sixty.

  The KPA pairs its nuclear capability with an asymmetric toolkit designed to offset the technological advantages of South Korean and U.S. forces. Bureau 121, the elite cyber warfare unit, comprised approximately 1,800 highly trained hackers as of reporting, and in December 2014 the Bureau was accused of hacking Sony Pictures and threatening consequences that led to the cancellation of the film The Interview. Vehicle-mounted GPS jammers with ranges of 50 km-100 km are already in service, with longer-range models and electromagnetic pulse bombs in development.

  A RAND Corporation study completed in 2020 concluded that a North Korean artillery strike on Seoul alone could produce over 100,000 casualties in the first hour of bombardment. The KPA's wartime strategic food reserves are estimated to be sufficient to feed regular troops for 500 days, while fuel and ammunition stocks amounting to 1.5 million and 1.7 million tonnes respectively are judged sufficient to sustain full-scale war for 100 days.

• 8. Scale and Structure

  ›

  The Korean People's Army Special Operation Force numbers 200,000 troops, which North Korea claims constitutes the largest special forces establishment in the world. The KPA's submarine fleet is similarly described as the world's largest. Total equipment in the ground force includes 4,100 tanks, 2,100 armored personnel carriers, 8,500 field artillery pieces, 5,100 multiple rocket launchers, and roughly 10,000 man-portable air defense systems and anti-tank guided missiles. The air force operates 730 combat aircraft, of which 478 are fighters and 180 are bombers, though much of the fleet dates to the Cold War era.

  North Korea conscripts males for 10 years and females up to the age of 23. The constitution's Article 86 states plainly: "National defence is the supreme duty and honour of citizens." Beyond the regular forces, the Worker-Peasant Red Guards, the largest civil defense force in North Korea, are estimated at 5 million personnel, organized from the provincial level down to individual villages and structured on a brigade, battalion, company, and platoon basis. The militia maintains infantry weapons, mortars, field guns, anti-aircraft guns, and equipment including multiple rocket launchers such as the BM-13.

  The annual KPA budget sits at approximately US$6 billion. North Korea's state news agency reported that military expenditures in 2010 consumed 15.8 percent of the state budget, though independent analyses by bodies including the International Institute of Strategic Studies have placed actual defence spending at roughly 25 percent of central government expenditure. In the mid-1970s and early 1980s, figures released by the Polish Arms Control and Disarmament Agency put the share between 32 and 38 percent. In March 2024, Kim Jong Un was photographed driving a newly developed tank alongside soldiers he described as preparing for war.
