By thickest part of the pz4 you mean
The sides of the hull
The sides of the turret
The front of the turret
The front save the one plate
The thinnest part of the Sherman being the entire tank unless angled,
Sorry but unless the pz4 tanker is an idiot he would win
My last post you can talk to you’re self I am sure you are familiar with that
Fun fact: The 105 Sherman can overpressure the Panzer IV H by shooting the front of the turret, the side of the turret, the back of the turret, the roof of the turret, the front of the hull, the side of the hull, the back of the hull, the bottom of the hull, it can overpressure through the external turret armor and the Schurtzen, and best of all it’s really not that hard.
