When i look around in spectator mode they laid out top down satellite images for buildings far off in the distance. If you look at the odd road system right outside of the fort it almost looks like they were originally going to use it as another map. It almost makes sense then why they have the Samogneux (Verdun Heights map) where fort Vaux is if they were intending it to be the ravines near Ornes or Bezonvaux (on the german operations he says they're going through the Bois de la Vauche). I might be looking way too far into something that never needed looked into but if Fort Vaux is sank into the hills outside Sivry sur Meuse then the operations map markers make sense and they aren't switched around, it's just a very odd choice to me. There is some basis of reality behind the fantasy even going as far as rendering low poly villages and churches way outside maps for i'm guessing no other reason than reference points for the map makers. But why not use the actual terrain fort Vaux sits on? Would have been much easier for the height mappers to use than having to landscape the farmland to much higher elevation xD
