[2022] BTR-ZD - is it a joke?

The year of the vehicle does not matter. How capable it is matters. If it is from the 70's and is worthy of being tier 4 because of its performance, then that is where it will go.

If the vehicle proves to be too powerful, then its BR will go up. BRs are mostly determined by statistical performance.
