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

[IceFire]

I'm just wondering if there is no problem at all here. Sure in a testing environment you can wax a dozen medium tanks with a high angle 37mm shot. I'm not sure if this is an issue or not... in real life you'd likely be dealing with small arms fire and maybe mobile AAA making this sort of repeated attack against a formation of tanks somewhat unrealistic.
