It eventually became the basis for the present national semi-militarised police force.[2] On 19 June 1953, its authorized strength was expanded to 20,000 men, a mixture of conscripts and volunteers equipped with armoured cars, anti-tank guns, helicopters, trucks and jeeps. By 1956, it had a strength of 16,414 men. Although it was not intended to be able to repel a full-scale invasion, the BGS was tasked with dealing with small-scale threats to the security of West Germany's borders, including the international borders as well as the inner German border.
