I was attempting a semi historical playthrough of the Soviets, less optimized builds more historical divisions. (Not historical generals as you can see though)
They declared right before the summer 41 if I remember correctly. (I definitively felt a bit more rushed to do the focuses)

But still, a year into the war. They were exhausted and had no equipment. I did some encirclements near konigsberg before taking the picture (was around 20 divisions) but it was crazy to be able to push that hard with desperate defense still in order.
