Ah, good idea getting Mrs B interested, that might help cut through the red tape with future game purchases.
Correct, I do leave out units if they played no real part in the battle so as to prevent them from playing too much of a role accidentally (ie. by getting released by LOS). However, I see no reason why I can't put the RIF into reserve back there as fixed status, I was probably being too harsh if that is why I left them out.
As for the name, you are correct -- it seems I left out "Royal" and have them listed as 1/Irish Fusiliers. I just checked my source OOB from the war department and it had it listed as Royal Irish Fusiliers so that might have been a late night OOB editing error. I will correct that in the next F14 update.
Thanks for the info!
