You're welcome! Thank you for telling a story that needs to be told.
Operation Barbarossa was pretty horrific, most of the time, all that gets taught is the awful statistics, not a peek into what was going on behind the statistics. The average soldier of the USSR suffered massive betrayal both from the results of Stalin's purges and Hitler's perfidy.
I remember a quote from Kalishnikov, that the world had the German invasion to thank for the invention of the AK-47, and that he'd rather have been known for creating the world's best tractors to help feed his fellow citizens.
