I actually did bring up both these points (in other threads though apparently). Command Panther could perhaps lose the coordinated fire ability and gain a better passive combat aura instead. I'd put Sturmtiger in Special Operations because it fits the doctrine theme way better than the JT. Combination of flares and Sturmtiger is good, but not as powerful.
I think JT is fine in Breakthrough. Perhaps it could go to Overwatch, Breakthrough could be given a Tiger I callin. For variety's sake.
If comand panter is in the mix again can we look into dropping the KT exclusivity. I belive this was preposed before but fell though during patchwork.
