Panthers vs. TDs:
Flanking is suicide and most attempts fail
AT gun have no mobility and easily neutralized
Shreck? haha
Can someone give the Allies some captured TD?
Panther will win versus a Jackson in a straight up fight though though, unless you dive with no support and get snared by infantry or hit a mine or something. Any other allied TD it's a similar story, even easier due to lower mobility stats and moving accuracy.
There's no need to flank allied TDs with Panther since Panther will penetrate any allied TD 100% of the time at any range. If you do decide to flank anyway the SU-85 is comparably easy to flank.
Shreck will penetrate every nondoc allied medium tank and TD 100% of the time.
How will TDs kill your ATG?
Captured panther or jagdpanzer or stug III g would be cool for allies I guess
