the Whittman issue will probably never be totally sorted, but I like Nestor would like to belive it was Joe Eskins that took the guy down.
Anyway back on topic.
fighting in Normandy will not be your typical Eastern Front wide open spaces tank maps, the countryside was full of what are called Bocages (hedgerows)
these are no normal Hedgerows as we know them, these are 3-4 feet thick earth mounds with trees bushes growing out of them, the roots of which act like rebar, this means you will not be able to drive your tank through them or over them as the are around 6-8 feet high in places.
read the following for a good idea of how both allied and axis used tactics to counter these obsticles.
