IS-2 in game some sort of OK if forget about:
- almost usless vet 1. Yep this can give a win in one of the hundreds of fights, which is so rare that it will be remembered for long time;
- RNG shots. IS сan one shot wipe full squad or miss in building the size of a train station. Yes, it causes frustration in both cases.
- nazi have best AT-weapons. All of them, from hand panzersherks to superheavy tank destroyers;
- IS-2 available in two doctrine. And one of them is realy...specific.

...Many times I noticed some individuals tried to compare armor penetration values of the 8,8-cm KwK 43 and the 122-mm D-25T. Unfortunately, these individuals paid no attention on different nature of those values: they were calculated by different methods. In short, the difference of calculation was about 25%. Therefore, it would be better to either increase Soviet figures on 25% or decrease German figures. Of course, the result would be very approximate, but it is much better then direct comparison...
