remove the sighting ability then. Remove it from all of the heavies. I don't know if the jagd has it, but remove from the elephant too. It already has spotting scopes. Alternatively I think I would support a marder style lockdown to all these tanks with range above 60(not including su-76, but we could

). Being able to remove the lockdown has a 5-10 second cooldown. If you have good support, it's no problem. If your cheesing, you might get pwned.
