The National People's Army were the armed forces of the German Democratic Republic (DDR) from 1956 until 1990.
The NVA was organized into four branches: the Landstreitkräfte (Ground Forces), the Volksmarine (Navy), the Luftstreitkräfte (Air Force) and the Grenztruppen (Border Troops). The NVA belonged to the Ministry of National Defence and commanded by the National Defense Council of East Germany, which was headquartered in Strausberg - 30 kilometers (19 mi) east of East Berlin. From 1962, conscription was mandatory for all DDR males aged between 18 and 60 requiring an 18-month service, and it was the only Warsaw Pact military to offer non-combat roles to conscientious objectors, known as "construction soldiers" (Bausoldat).
