They didn't use the command structure you're referring to because they didn't get them. Very silly assuming they just ignored them because of some principled stance.

Agreed communism is incompatible with fascism but that's historically convenient because Stalin was a wolf in sheep's wool on that topic. His government modeled many fascist behaviors quite readily.

Edit also I'd say declaring the workerbee vs command distinction is a clear goalpost move.

I asserted that the soviets took Nazi scientists and technologists, and they did.
