There is no valid reason why a panzer IVH with a 48 caliber 75mm gun can shoot another one 6 times in the rear of the engine and turrent befor getting a kill.
Rear hits are still very far from rational.
And you can see the tracks of enemy as they climb the reverse slopes of hills. Makes it easy to lead them as they emerge.
And the Panzer Pintle mount should have a 360 degree field of view. I realize that it wasnt a 360 degree mount but the gun could be trained over 360 degrees. There should be know blind zone for the mg..it should just be unable to keep tracking in a greater then 360 degree circle.
