Well, it depends on what story you want to tell, and what dimension you want to emphasize.

What is often overlooked is the whiting over of the disastrous policies of Stalin, just to keep his power base in tact.

But in terms of numbers, DePuy is the guy to go to.

Compare:

According to "Undying Regiment" data taken from the State Planning Committee now opened, the total number of lost people in the USSR in 41-45 was 52 mil. The natural number would be about 10 mil. So, the number of losses was counted as 42,000,000 people. Here are ALL losses, due to hunger, illnesses due to malnutrition, KIA, civilians killed, died in camps and other reasons. Of these, military losses consisted about 19 mil.

During the first three months the Soviet losses were about a million/month. They surrendered, because mostly they hated the SU.

Interestingly, the Cossacks. These were eventually "repatriated to the Soviet Union after war, causing a rebellion by Georgian soldiers serving in the Wehrmacht during the period May45 - June 45 in several areas that were not yet occupied by Allied forces in Northern Netherlands. The reason was, as expressed by General Blaskowitz in April of 45, surrender was not a bad idea but then assurances had to be given that Germans troops would be considered POW and not delivered into the hands of the Soviet Union to perform slave labor in Siberia. Such assurances were not given. They were labeled: captured enemy combatants.

Then we have Depuy (Number predictions and war)

Germany remained man to man superior not just to the Western allied armies right up to the end of the war but considerably so to the USSR. Even by at Kursk Germany had a 256% fighting effectiveness advantage to the soviets, 1 German soldier was equal to 2.56 soviets in fighting ability.

By 44, this advantage had dropped to 180%, one German soldier being equal to 1.8 soviets. Depuy study is exhaustive, and just goes to show this guy above does not know what he is talking about. Oh by the way Depuy factored in the defensive advantage the Germans had, this figure is minus that advantage. So on an even field basis, 100 German were equal to 180 Soviets. The soviets won because of overwhelming numbers, Hitler's stupidity and the second front, THE USA!

Allies mobilized against Germany 40.4 million, Germany Mobilized 12.5 million. Allied casualties 23 million, German 10.1 Million. Score effectiveness Allied .25, German 1.84. Which means one in four Allied soldiers inflicted a casualty on the Germans, while each German averaged nearly two Allied casualties. Even after Depuy adjusted for defense posture the German score rating was 1.42. Which was five times as great as the Allies

Sobering statistics, no doubt. The question becomes: What is the reason for this? And this is reason is the real story.
