Is the Kursk campaign viable?

[Mike Abberton]

Are your quick victories coming from bypassing the heavy defenses at the shoulders and attacking through the weakly held remainder of the salient? I think that is a fairly well known limitation of the Kursk campaign, that if the German deviates from the plan, i.e. doesn't attack at the shoulders, he can win fairly easily.

A campaign game then, might require a house rule that the German player sticks to the general OKW plan and attacks along the historical attack routes.
