I don't know if any one else has posted or tried this yet, but there is a relativley easy way to rename armies, and though I haven't tried it yet, to rename just about anything.
All you have to do is save your game, then open the file with an editor like Notepad. Scroll through the other countries til you get to yours. Then scroll down the list, it's a bit long, but you should find your list of armies and navies and shortly after the list of historical leaders. Now, you should see the army's current name in quotation marks. Just highlight the name (but not the marks!!!), and type in what you want instead. When you reload the game, voila! That 'Home Army' stationed in Calais, is now the 'Imperial English Army', and that 'Red Squadron' is now the 'Irish Squadron'.
