Johnson Barracks, Führt, 1957 (Source: John Ackerman) The sign hanging over the main gate was there only for a few months in 1957 as the 3/8th Cav, an 8th Infantry Divison unit, was soon thereafter moved to Coleman Barracks (Mannheim-Sandhofen) as part of the BIG SWITCH operation in which the 4th Armored Division and the 8th Infantry Division swapped areas of operation.
