Thank you for contacting our Customer Support for wargaming.net.
I'm sorry for disappoinment for your tank, but please keep in mind we as the support team not allowed to do any in-game changes/upgrades.
For the tank we can't help because basicly to use the OTR option the tanks has to be a premium one.
Sorry i couldn't help.
If you have any other questions, feel free to come back to us.
Kind regards.
Alper Johnson
