I'm probably missing out something, since i am fairly new to the game, but i couldn't find an explanation for this:
I could successfully launch grand offensives on the Austrian front with Russia and on the German front with France, so ; have no problems with launching offensives. But when i tried this with the British 1. and 2. Armies in Belgium, i just couldn't. When i open the Grand Offensive window in Belgium, it only shows the Belgium Army. What am i doing wrong?
