Might be old news but I heard one of my PE units saying words to the effect that "Kampfgruppe Lehr was ready for action"
Obvious conclussion that the PE are meant to represent the Panzerlehrdivision in the game. Lehr were heavily involved in Caen so it makes sense.
Interesting as Panzerlehr were a Heer division which of course means they did not fall under the remit of the Waffen SS.
Might have been a politcally more correct choice on the behalf of the developers to steer away from the Waffen SS divisons and the associated war crimes linked to some of that arm (Das Reich being a prime example).
I had always assumed the PE were a Waffen SS unit and it seems not. Just a little observation for the WW2 nuts amongst us!
