The Rhodesian Armoured Corps—the "Black Devils"—was the only standing armoured battalion of the Rhodesian Security Forces. During World War II, it took part in the Allied Spring 1945 offensive and the Battle of Monte Cassino as part of South Africa's 6th Armoured Division. The unit was among the first to enter a liberated Florence in July 1944. Prior to 1963, its crews were trained in the United Kingdom or Aden Colony and were known as the "Selous Scouts" under the Federation of Rhodesia and Nyasaland
