Here is the ideas for completely different set of tournaments
Iron certain tournament
Soviet tanks on USF and UKF, let see how good Penal do against Tommies and Riflemen...
The war of independence tournament
USF take on UKF, lets see if M36 can take on the Comet...
Valkyrie tournament
OKW vs Wehrmacht lets see if the Elephant can take on the King Tiger...
Imo this could be actually quite fun...
