And for those who say "bUt the SoViEts hAD thE Most caSuALtiEs", yes, they did, because they were devastated by Operation Barbarossa. In the Battle of Kursk, for example, the Germans lost fewer tanks than at El Alamein: the reason for the massive tank casualty numbers was because the Soviets lost thousands of tanks. The reason this was still a serious blow to the Germans was because at this point, they didn't have that many tanks left anymore. Also, while British and American lend-lease was not at all a vital part of the Soviet war effort, it still contributed 400,000 trucks and jeeps, 14,000 airplanes, 13,000 tanks, and 2.7 million tons of oil and petroleum products.
