The big tank battle took place on boards 4 and 6 pitting German armor efficiency and mobility against Soviet AT fire power of 4, 6 & 7, depending on the firing tank & target the Soviets would only need a dice roll of 6-9 on the AT table to KO a German step. The tank battle come down to who won the initiative and got to shoot first, the Germans had the upper hand at first but that all changed when the Soviets got some double step losses from their SMKs, T28Cs and T35Cs against the Pz-IIIs. After that it was downhill from there for the Germans.
