The Korean People's Army constitutes the military defence forces of North Korea. Kim Jong-un is the Supreme Commander of the Korean People's Army and Chairman of both the Central Military Commission and National Defence Commission. The KPA defence consists of five branches: Ground Force, the Navy, the Air Force, the Strategic Rocket Forces, and the Special Operation Force. The Worker-Peasant Red Guards also come under control of the KPA. The KPA faces its primary adversaries, the Republic of Korea Armed Forces and United States Forces Korea, across the Korean Demilitarized Zone, as it has since the Armistice Agreement of July 1953. As of 2013, with 9,495,000 active, reserve, and paramilitary personnel, it is the fourth largest military organization on Earth.
