Aug. 14, 1961 - A company of American troops staged a simulated city battle in Berlin today. The training maneuver was held in a mock town built by the U.S. Army only 200 yards from the West Berlin-Soviet Zone border. Staged by about 200 crack troops of the Sixth Infantry, the "battle" involved tanks, artillery, and a helicopter. A similar maneuver will be staged tomorrow for Brig. Gen. Frederick O. Hartel, commander of the US. Army troops in Berlin.
