The Soviet’s prior experience in Eurasia had been to surround their targets and wait for them to surrender or succor to attrition. You can even see that today with Russia and Ukraine. But their past shows how because they were so large and where they were located, they could pin/surround their enemies. Which is why the Cold War was so difficult, because of where the US and Soviets were located.
The US was very different from the Soviets. While this was some time ago the US had been accustomed to full frontal attacks and fighting head on. We can see this In the revolution, Spanish war, Vietnam etc. When we look at ww2 we can see that they continue to do this. With Japan that sent full frontal attacks in the pacific battle. And they sent a large number of their forces to aid the Allied powers.
