Guys, I dont think anyone is arguing that a 7.92mm bullet should be able to take out the main gun of a PzIVH or the bow MG.
The results are interesting though, because it shows that the front turret and front hull armor has not been penetrated by the 7.92mm or .50cal bullets.
It would appear that the PzIVH armor model protects the turret and the hull, but the gun and the mg is not protected by said armor model.
As for the tracks, I dont think anyone is arguing that a 7.92mm bullet or .50 cal bullet should be able to detrack a PzIVH either. The most probable reason for the damage to the tracks is that the tracks are not considered armored, but that is just my speculation.
It will be interesting to see if the 7.92mm or .50cal can take out the engine from the side and rear though.
