Yes, the Russian were tenacious fighters, and produced good rugged weapons systems. Of course, take away all the lend-lease equipment and food, and a lot of that manufacturing capacity goes towards making the millions of transport vehicles that came from Detroit and food that came from America’s heartland. How many close run fights are lost instead of won, because the Russians don’t have US or British armor to fill the gaps, or a fleet of Edsel and Ford trucks to move reinforcements and supplies, and the troops are starving, because they don’t have US rations in their bellies?
This whole revisionist history that paints a picture of the Russians defeating the Germans in the east all on their own is ridiculous.
How much help did Russia get from the west in the battle of Stalingrad, early in the war. Capturing 80,000+ and turning the tide of the war?
