During the Socialist and the Warsaw Pact era (1947–1989), the Soviet Southern Group of Forces, 200,000 strong, was garrisoned in Hungary, complete with artillery, tank regiments, air force and missile troops (with nuclear weapons). It was, by all means, a very capable force but which had little contact with the local population. Between 1949 and 1955 there was also a huge effort to build a big Hungarian army. All procedures, disciplines, and equipment were exact copies of the Soviet Armed Forces in methods and material, but the huge costs collapsed the economy by 1956.
