This shell is not only broken in the balance sense, but is literally broken in its overpressure.

I think it is alright since it’s not a ru vehicles.
BEA1 has a nearly 60mm HE pen ,i found armor less than 50mm in most of your examples unless the merkawa.And maus has a bugged overpressure model. So i think most of your examples are not a bug
The 279 is designed to wishstand Nuclear Blast pressure.
The T95 gets overpressured from the rear sides where it isn’t vulnerable, plus the Tracks and suspension should eat the blast otherwise.
If this is “intended”, which would be insanity, this vehicle needs to go up in BR by a lot.
