Panzer Campaigns Kharkov 43 - Keep the Infantry Moving
Operational and strategic mobility is are usually bound to the road network.
In PzC's Kharkov 43, the winter weather conditions are forcing me to conduct a good portion of the tactical maneuvers near the roads. In particular, infantry. Not that they can't move through the open ... It's just too taxiing for them to do so.
This company from the 320th Inf. Div. will be walking roads until it makes contact. The highlighted hexes are the reachable ones. Note how mobility is double if the grunts keep their feet in the road. Any movement aside the road will reduce their mobility to half. From the "Gross Deutschland leads the way" scenario.
