Generally, it is second doctrine which has access to IS2. It is hard to use. At 10CP we have double t34/85 and at 11CP IS2. But is has limited use. When we play T1+T2 and wait for call ins. But on 4CP ostherr have medium armor. Other idea is playing T2+T3/T4 but we only have conscripts as core infantry. And maps of course, this commander should be used only on maps like Lienne Forest, where we have warranted fuel point.
Help me maybe it is interesting commander, but everyone uses shock rifle. Someone expirianced, should do guide for soviet commanders
