Kasernierte Volkspolizei
The Nationale Volksarmee (NVA) was the largest military organisation in East Germany. It was formed in 1956 from the Kasernierte Volkspolizei (Barracked People's Police), the military units of the regular police (Volkspolizei), when East Germany joined the Warsaw Pact. From its creation, it was controlled by the Ministry of National Defence (East Germany). It was an all-volunteer force until an eighteen-month conscription period was introduced in 1962. It was regarded by NATO officers as the best military in the Warsaw Pact.
