I have heard a lot that wwII eastern front was basically a war of attrition with lots of poorly prepared Russian troops being thrown at the nazis and the nazis eventually losing bc of fighting a two front war but also taking on such a geographically and numerically large enemy.
Also due to them not being prepared for the level of cold that the soviets could handle.
But are there instances both of strategy being superior in some red army battles , or of skilled groups of troops in red army winning battles not just as attrition?
