The first one, the movie First Squad looks interesting mostly because being in America and the cold war you did not get many series or films detailing things from the perspective of the USSR. It was only really up until 2000 that you started seeing historic films made from the perspective of the Soviets as they battled to the bitter end to drive off the Nazis. Good job by including the links. Thank you.
One interesting fact is that while the Soviets got the Nazis off their land they actually took heavier casualties during the fighting. But the golden sickle proved to determined for the black swasticka.
