i think the best way is to have new buildable units and the old one (panthers, tigers, panzer IV) call in as battlegroupsalso some group zeal for especially Panzer III could be so that more PIII then they are better and can more easily deal with russian tanks
Going back to this, the group zeal might be quite a good idea. It could represent the Blitzkrieg tactics as well as the excellent radio communication the Panzer groups enjoyed. In gameplay, it would also be interesting to see the weakest MBT of the factions grouping up to defeat more advanced tanks.
I would think the Panzer III would be the MBT for sure in the Ostheer. The advanced tank would probably be in the form of the panther, since these were so numerous on the EF. It makes me wonder where a Tiger would even fit into the faction. Perhaps the Ostheer may have a 5th tier building, which creates the equivalent of vet 3 Wehrmacht tanks?
hmm what units share PE and Wehr? right now i can remember only panther tank
on wikipedia.org the Panther is medium tank http://en.wikipedia.org/wiki/Panther_tank
