I liked the Graphic map presentation..
The victory at Kiev also supplied the German Army with massive quantities of equipment they used thru out the war.. The 76.2mm Dual purpose Field gun was a good example.. They captured 10's of Thousands of them, and mountains of ammo.. Used them on all fronts, served along side the PAK40 till the end of the war..
The Marder II and III, were actually more likely to utilize the Russian gun, than a PAK40..
The fact that the Soviets survived the losses at Minsk, Kiev, and Smolensk, is incredible.. The path to Moskow was wide open.. And Zhukov and the Armies of the east, hadn't been moved yet.. Only The delaying actions of the slaughtered Workers Battalions, that were thrown into the gap, and General Winter, saved them..
