Are you sure that BMP Armata armor stats are correct?
I know from all the available sources that BMP and T14 have the same chassis and addon armor packages, active and passive, so same protection value, and in the game it's not.
In addiction to this, according to the available photos, T14 and T15 have not only front ERA but Side and Top ( and in the game T14 has only front, and T15 front and side).
So, we can talk about T-14 protection, but T15 BMP is heavily underprotected in the game, at least in hull stats (I think turret is fine).
T15 is less protected than BMPT Ramka tank support vehicle!!
I suggest a modified OOB until next patch.
Thank you for the attention.
