I realize there may be technical issues restricting the implementation of this change. However, if they can be overcome it would add a bit of historical accuracy if there were
a separate GHQ for the BEF (English only) and one for the French (GQG), with the Belgian units falling under one or the other of these major headquarters, not just one GHQ for the western Entente, since these two national entities coordinated so poorly even after Joffre became Supreme Commander. Perhaps the AEF under Pershing warrants another GHQ as well, just for US units.
