D-Day is postponed due to weather, and more weather, and more weather. WAllies eventually only meet the Soviets significantly further west, maybe only on the Rhine.
It is a Soviet narrative that dominates the post-war zeitgeist, as it is a Soviet occupation of the majority of Germany, and a Soviet trial and bullet in the back of the head for the vast majority of the officers of the Wehrmacht and of the Nazi Party, the Gestapo, the RSHA, the Abwehr, university staff and other intellectuals who survived the Nazis , landowners, factory owners, lawyers, and priests, and the justification for the Katyn-like purge across Germany is that they were all just as much a part of the Final Solution as the einsatzgruppen.
To my knowledge when the Soviets formed the armed forces of East Germany they also made heavy use of former Whermact veterans. I believe they were mostly enlisted men and lower officers but the Soviets in general tended to make use of heavy use of much of the former Nazi Apparatus. It's just kind of one of those things. Hard to run a country without a beuracracy and in East Germany's case a secret police.
