The Mongolian Armed Forces is the collective name for the Mongolian military and the joint forces that comprise it. It is tasked with protecting the independence, sovereignty, and territorial integrity of Mongolia. Defined as the peacetime configuration, its current structure consists of five branches: the Mongolian Ground Force, Mongolian Air Force, Construction and Engineering Forces, cyber security, and special forces. In case of a war situation, the Border Troops, Internal Troops, Judicial enforcement agency and National Emergency Management Agency can be reorganized into the armed forces structure. The General Staff of the Mongolian Armed Forces is the highest professional military management organization of the state military organization and operates independently from the Ministry of Defence, its government controlled parent body. The official holiday of their military is Mongolian military day on 18 March, the equivalent of Defender of the Fatherland Day in Russia and PLA Day in China.
