A Burning Soviet T-34

Aftermath of the repel of a Soviet tank attack by German forces in the Eastern Front: a hit, burning T 34 tank. The picture was taken by Kriegsberichter Artur Grimm, early or late 1943 (winter). The T-34 seemed impervious to German weapons and able to destroy German tanks with ease. Panzer commander General Heinz Guderian saw the heavy losses inflicted by the T-34 and realized what a game-changer it was, outclassing his own Panzer IIIs and IVs: “Up to this time we had enjoyed tank superiority, but now the situation was reversed,” Guderian wrote. “The prospect of rapid, decisive victories was fading in consequence."
