Remove it with the Elephant, and take the lesson "don't have 2 supertanks that shoot halfway through the map when every other tank can only shoot 50 ft away".
The elephant and the Isu should have never been in multiplayer. Both are broken units that can only be countered by enemy mistakes. Hell, bombing runs and arty don't even do shit, just a crew shock.
Just broken
Uhm Russian IL2 Bombing run dont do crew shock, it can almost kill a full health Elefant.
