Insignia
As far as I can see, most of the SS personel in the pilot is wearing Polizei Division armbands, but I don't believe that particular division was ever used as an occupation force in France, does anyone have any insights on this?
And of course there is the matter of the WH markings on most of the vehicles used by the SS in the same episode, normally SS outfits had their own motorpool with it's own markings, although later in the war they'd probably make do with whatever they could get their hands on.
