Many thanks for the quickly answer.
It's a pity for a no dinamic campaign. The front line in many cases moved on and back several times before the victory in one area.
I remember a Pc game called "1944 across the Rhein." It was a very good game similar at TOW. You managed a Kampfgruppe and you drove each Tank.
In that case the line of the front changed in base of your battle result. It was very interesting.
Consider this possibility in the next future.
