Yak-9T - incredible firepower (or maybe incredible tank's lack of armor?)

Japanese tanks can be killed by bullets as small as .50cal.
And what I want is some armor model that takes bullet size (or better remaining bullet energy after penetration-then for APHE the additlional chemical energy could be used, too) into account. So that not every penetrating hit is a kill.

Hmm, T-34 did use diesel fuel, that does not burn instanteneusly, must have been a lucky hit.
