When playing as the Axis, I generally try to engage from longer distances when possible. If your using the heavier armor this has obvious avantages, but it is usually a good play with even Panzer IVs. They can more than match a regular Sherman for firepower, but even more important they have a smaller silohoutte. If yoo're forced to get in close, things get a bit trickier. The differences in firepower and armor become much less significant and most Allied armor has medium to fast turrets. Axis armor has to make god use of the terrain at close range, even with the heavies, to protect it's weakspots.
