The Soviet Union vs Germany and Japan (KIA only): 1. Germany vs Soviet Union (07/1941-12/1944) 1.420.000 German KIA vs 4.700.000 Soviet KIA 2. Soviet Union vs Japan (08/1945) 12.000 Soviet KIA vs 80.000 Japanese KIA (the soviets traded their soldiers in 3 to 1 for the Germans, for comparison, in Italy and Africa, when the allies didn't have total air superiority, they traded their soldiers for 2.5 KIA for every German KIA). The Red Army was not bad at all, they lost millions because that was what it takes to defeat the most formidable fighting force of the XX century. Vs the Japs the red army was as good as the American army, maybe better.
