Iron CurtainThe Iron Curtain is a political metaphor used to describe the political boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991. The term symbolizes the efforts by the Soviet Union (USSR) to block itself and its satellite states from open contact with the West, its allies and neutral states. On the east side of the Iron Curtain were the countries that were connected to or influenced by the Soviet Union, while on the west side were the countries that were NATO members, or connected to or influenced by the United States; or nominally neutral.
Combat Groups of the Working ClassThe Combat Groups of the Working Class (Kampfgruppen der Arbeiterklasse, KdA) was a paramilitary organization in the German Democratic Republic (GDR) from 1953 to 1989. The KdA served as the de facto militia of the ruling Socialist Unity Party of Germany composed of party members and politically reliable working people, based on dictatorship of the proletariat principles, to be deployed locally to fight civil unrest or invasion. The KdA was a civil reserve force tied to the GDR's Ministry of the Interior and the Volkspolizei, reaching 211,000 personnel at its peak in 1980.
