The National People’s Army (NPA) (German: Nationale Volksarmee - NVA) was the name used for the armed forces of the German Democratic Republic, created on March 1, 1956, six months after the formation of the West German Bundeswehr, from the Kasernierte Volkspolizei (Barracked People's Police). It was preceded by years of preparation during which former Wehrmacht officers and communist veterans of the Spanish Civil War helped organize and train paramilitary units of the People's Police. With its German appearance - including uniforms and ceremonies patterned after older German military traditions—the doctrine and structure of the NVA were strongly influenced by the Soviet Armed Forces.
The NVA was first established in 1956 and disbanded in 1990; it did not see any significant combat. Its participation with the Soviet Armed Forces against the Czechoslovak interim government during the Prague Spring of 1968 was cancelled at the last minute. However, there were frequent reports of East German advisors working with communist African governments during the Cold War. The NVA was disbanded in 1990. Its facilities and equipment were handed over to the Bundeswehr. Most facilities were closed, and equipment was either sold or given to other countries. Most of the NVA's 36,000 officers and NCOs were let go, including all officers above the rank of lieutenant colonel.
