Even for Armata T-15 there has been some testing with 57mm weapons.
In game we have IMHO too low T-15 protection values in comparison with T-14 tank. Remember that we are talking about the same shared platform. The only difference is that the chassis is "inverted". The rear of the tank with the engine, in the IFV is on the front. The front of the tank is the back of the IFV but there is a door for the soldiers. So there is obviously a difference in armor values but in my opinion in game there is too much difference between the two models

"The T-15 Armata is one of the most protected, if not the most protected IFV in the world. It seems that in terms of protection it is superior to most heavy armored personnel carrier and heavily-armored vehicles such as German Puma IFV.
It has newly-developed base armor, made of steel, ceramics and composite materials. Also it has Malakhit add-on explosive reactive armor, that is claimed to be of new generation. A front-mounted engine provides additional protection."
In my opinion, like Namer has armor values similar to Merkava, ARMATA T-15 IFV should have protection values similar to ARMATA T-14 TANK
