The developers are well aware of these facts, so the T-72A’s armor seems very accurate to me.
The armor of the T-80BV/U and T-72B raises a few more questions.
For example, the T-72B had different armor packages, and the game features the latest one.
I’ve seen estimates of 530-600 and 550-620. The game has 530, which is the minimum.
For the T-80BV and U, there are suggestions that the T-80U should have armor made of 50-30-50 steel, but its durability, taking into account Kontakt-5, should not be much lower than the current level (620-630 according to some sources), while it currently stands at 630-640.
Research into this area could yield interesting results.
It’s 120 - 140mm in real life as far as I am aware, but that isn’t really that important considering the beak seems to be a Gaijin’s way of keeping the main composite underperforming to a degree of “what the hell were they thinking” considering D-technology was capable of providing 650mm RHAe KE by itself when put into the hull, and we don’t have that in the game…
Even then, 2A7Vs armor is still massively underperforming :P
Fun fact: this armor was put into Leopard 2A5s turrets from the get-go, and according to German documents, C-technology should perform vastly better than it currently does in the game, as it was tested against KE munitions capable of perforating 480mm RHAe and it stopped them as of 1988 i.e after it finished development, currently in WT it only provides ~430mm (due to Gaijin using sources that were made before it could properly finish development).
“It can” is a forgone conclusion, it has been proven how much it offers multiple times, Gaijin is just insistent that it doesn’t exist (“We believe it is a clear marketing lie” lmao) even though German documents very clearly state it does as a main armor package.
Feel free to hit up BAAINBw by yourself(!), that is what BMVg demanded from Clouth, KM, IBD and B&V, oh and also, don’t ask me in DM’s for the full source like you did with DM53/63s technical drawing lmao, I was genuinely close to reporting you to community managers seeing as you were fishing for a classified source :)
As you said. combination effects. But also, 16mm at 68 degrees is 43mm thick, it was a high hardness steel which is 1.25x, but KE is 1.2x efficient at that angle, thus the improvement is 1.042x, whic gives us a 45mm improvement.
