M60, it seems like you could achieve a significant breakthrough if you concentrated your troops and attacks. What would you say the downsides to that strategy are?
From my experience (on both sides), a successful breakthrough stretches the Wehrmacht thin, which makes winning battles easier, and it can potentially trap stragglers to encircle and destroy. Additionally, in blizzard conditions, there's usually no serious threat of counter attack.
It is possible that what you say is true, and a fair number of folks would probably agree with you, but that attempted breakthrough would have been most effective in open terrain. That would likely have been somewhere around Kursk. That would have left the opposition in control of the wooded terrain northwest of Kursk that would have been a good jumping off point for his 1942 offensive. In order to deny him that ground, it was necessary to concentrate my best troops in that area. Had I pushed successfully west from Kursk, I'm not sure how much more exposed those same forces of mine would have been come April-May.
Overall, I'm accomplishing what I had first set out to do, and the lack of a significant breakthrough really hasn't been a regret, Not yet anyways.
