Just something I posted on the British Army's thread:
If this is still active, you should rename it - perhaps the 'First Army' would be suitable. The reason? If I start a regiment, I wouldn't allow it if someone started a company with a regimental affiliation of my own regiment. The same goes vise versa for if I started a regiment, and someone made a brigade that by default involved me - Why would I want to be under their command by default? Make a made up army, that doesn't envelope every single regiment there ever was under 'The British Army'. Make it "Flash's Army of Great Britain and ...", etc or "The First Army of Great Britain", would be a appropriate. That may, people may make their own armies as well, without any conflicts - e.g. "The Second Army of Great Britain".
I can't exactly force you to change but I'm just saying.
