And, in the context of this thread, giving the Germans "equal resources" at Normandy, who has which tank or AFV is largely irrelevant. What matters is what ships are present. Any concentrated tank assault will whither and die in minutes under naval gunfire. Tigers, Panthers, Stuarts, it doesn't matter. A deluge of even 6" shells such as Savanah or Philidelphia delivered on German tank attacks at Salerno proves this point.
One such cruiser can deliver 60 to 90 shells a minute accurately up to as much as 25,000 yards away. This is equivalent of a whole field artillery regiment or more on the ground.
If the Allies have a navy and the Germans don't (and, there is absolutely, positivitely no way Germany could match Allied naval power) the Germans lose. Its that simple.
