The Killing Machine Wittmann’s official tank was Tiger No. 205 (depicted above), although for the attack on Villers Bocage on 13 June 1944, he used First Sgt. Kurt Sowa’s Tiger No. 212. He also used Sowa’s crew aside from the gunner, for which role he chose his old friend, “Bobby” Woll, a fellow panzer ace from the Russian front.
