The Western German Army didn't have the name Oberkommando West, The OKW in real life was the Oberkommando der Wehrmacht, which had some control of the Western Front, North Africa and Italy. I would suggest the Western German Army to be called the Westheer or at least Oberbefehlshaber West (OB West) that commanded the Westheer in the Western Front. The reason why I putted this in Wishlist is because I didn't really know where to put this.
Note: I don't have the game yet, but I plan to have it next month.
I am just posting this just to make sure the name is more accurate.
