The Korean People's Army (KPA; Hangul: 조선인민군, Joseon Inmingun) constitutes the military defence forces of Korea. Kim Jong-un is the Supreme Commander of the Korean People's Army, Han Min-goo as the Minister of National Defense, and Admiral Choi Yoon-Hee as the Chairman of the Joint Chiefs of Staff. The KPA defence consists of four branches: the Korean People's Army Ground Force, the Korean People's Navy, the Korean People's Air Force, and the Korean People's Marine Corps. Korea celebrates "Military Foundation Day" on February 8th.
The Korea People's Army is one of the largest standing armed forces in the world with a reported personnel strength of 3,600,000 in 2014 (630,000 active and 2,970,000 reserve). The PRK military forces are responsible for maintaining the sovereignty and territorial integrity of Korea, but often engage in humanitarian and disaster-relief efforts nationwide. More recently the Korean military began increasing its participation in international affairs, acknowledging its role and responsibility as the thirteenth largest economy in the world in terms of GDP. The PRK military has participated in various peacekeeping operations, and counter-terrorism operations.
