Keep on-topic comrades !
The problem are the heavy tanks of the red army and for this job u need something heavier then Pz III.But what for a tank?Panther? Tiger? Nashorn?All in all those 3 tanks would have a qualification to be part of the Ostheer because they were developed out of the impressions of the eastern front. They were designed to stop and destroy red tanks and they were symbols for the battle of the eastern front ( try to image a battle of Kursk WITHOUT Tiger or Panther!!! Impossible! ).
What will be the Tiger's role in the EF?
Perhaps some of u had seen the Was ist das-Thread?
Your dreams have been set very low
