This is my first shot at making an army for Mighty Armies, hopefully it's correct. Aquilonia relied heavily on heavy cavalry with heavy infantry and archers on the flanks.
The Black Dragons (Cavalry) and Black Legion (Infantry) are both elite guard units so I gave them both "Disciplined" and "Fearless". I think those are appropriate characteristics.
The Bossonian Archers were given both "Mobile" and "Long Range", I consider them more of Ranger units rather than just archers.
Aquilonia is probably the strongest army, so it looks pretty strong. I hope I haven't over powered them too much.
