Following the end of the Second World War, British troops in Germany were deployed along the international borders of the British zone of Allied-occupied Germany to control the flow of refugees and prevent smuggling. They were replaced in 1946 by the Frontier Control Service, a civilian frontier force administered by the British Control Commission of Germany. It went through a series of names thereafter: the Frontier Control Service from 1946–49; the Frontier Inspection Service, 1949–55; and British Frontier Service, 1955-91.
