He didnt say that it is immune he said that the “Zbd04 can survive 25mm dart”, which is true as around 75% of the tank does resist the 25mm as the areas that hit the transmission are survivable shots.
It isnt really an “small” portion, the hull of this is pretty large and the bmd isnt the same in this regards as no part of the tank actually resist the 25mm apfsds, in fact you can pen the bmd 4 with a .50cal at short range…
It isnt, you keep having the apfsds, twice as many missiles far better protection and the LWS, with the apfsds it would be on par as you would only trade the mobility for the protection but as it is now it isnt on par.
I am pretty sure that this is on topic as im talking about the BMD4…
