Someone who knows WWII armor answer this for me... I'm too lazy to dig for the answer:
The 75mm cannon on the Pzr Mk IV and the Pzr V are the SAME or DIFFERENT? Im under the impression that the projectiles were the same, just the case was different (more capacity for the PzrV rounds). Also, I'm under the impression that aside from the lack of top notch armor and a high speed, the Pzr Mk IV and its cannon proved to be a good match for all but the biggest Soviet armor of WWII. Yes?
Oh... and no, I dont think we need the Panther. The PzrV would not fill a role tha is void right now. WE have the T34, the Pzr IV, and the Firefly and that is more than enough medium tanks in a WWII air combat sim. I say we need a tank destroyer first. After that, it is time to debate more.
