I think these "SS officers" in the trailer (and movie) are Ordnungspolizei
This was a police organisation answerable to the Interior Ministry, though many members held dual rank in the SS, especially the senior officers, and by 1943 the Orpo was practically under SS control. It was the primary police organisation in the Reich following the dismantlement of Germany's regional police.
They were known as the GrΓΌne Polizei (green police) because of the colour of their uniforms.
