Hello, last before update:
Are you sure that T80BVM (unit 046 OBAT 11) has the same base armor values of T80BV?
I think that like other tanks in this game, to correctly simulate protection improvement from ERA upgrade, the steel and heat values should go up (in a similar manner like T90A-->T90M in game with Relikt armor). I suggest armor values similar to T72B3.

"The protection of the tank front from all types of shells has been increased 40-55 percent and the protection of the sides and back was also upgraded."
From other (and the previous) sources, I read that the tank has the latest iteration of Refleks ATGM (9M119M, in game is Invar-M) and not the old Kobra (like in game), and it sounds logical for an upgrade.
