This post is completely wrong. You should have said: 'If the Soviets were always the same as they were in 1941, they would have lost the war'
They nearly did remember despite the soviets having rather massive advantages . If the Americans didn't help the soviets out with land lease, a western front and the complete destruction of germany's industrial capabilities i dont see how the soviets would have won if the soviets kept fighting that incompetently.
The Soviets were 'incompetent' in 1941 and up to the fall of 1942. The Germans and their allies attacked while the Soviets were reorganizing their entire armed force- they were 20 months into a 32 month program. The Soviet mechanized forces were destroyed in the first two months due mostly to the fact that they were only half formed. Afterward, the Soviets suffered from a cascade of misfortune and having to send hundreds of marginally trained reservist divisions to the front- outmatched by German formations due to lack of time.
They improved continuously though- something that the Germans did not achieve themselves. The German high point was 1941 (3 army group offensive) and they became weaker by (2 Army group offensive) Typhoon 1941 and (1 Army Group offensive) Blau 1942. Kursk was smaller than Blau 1942 and defeated by the Soviets in little over a week. The German twin pincers did not even get anywhere close to kursk.
Soviets were on par with the Germans during the winter of 1943. The Victory at Stalingrad destroyed all hopes of German strategic victory.
They surpassed the Germans and Axis allies in the summer of 1943. From the Summer of 1943 onward, Germans would no longer be capable of penetrating Soviet defenses at the operational level/operational rear. Soviet defense strategy had improved dramatically.
Lend Lease only started appearing in significant numbers AFTER they won Stalingrad.
By 1944 and 1945, Soviet operational art had matured and surpassed that of the German although they were still let down at the tactical level.
The Soviet's greatest operation would probably be Operation August Storm in Manchuria in 1945. The Soviets peaked in 1945 and the Germans peaked in 1941!
