Werwolfs? Never heard of them and this is the point where I can't agree with you: I think there is really no need for such a unit. Also, nobody knows them. Sounds like Overkill-Partisans to me. BTW: I've written a light version of my concept. Check it out here.
To me it seems that Werwolves weren't important in the war, when their greatest known "success" (killing an inocent civilian) was made by Luftwaffe and Wehrmacht.Desperate try to win the Endsieg, nothing more. Maybe Lord Rommel can tell us something more about them and if they're worth being part of EF.BTW: Das Heimatland, not Die Heimatland.EDIT: WTF I think I'm too tired...
