On related note, that layout in army management is stupid. First impression you get if you don't pay much attension when moving troops left is as if you'd be moving them to defense cause "defending army" is written right above it. Everyones first fights are always against map and if you move troops there there is no "defending army" written just above "currently selected army", so first time you go to army management from town it leaves impression like you have only this one type of active army which works for defense during the times when you are not fighting. So many people have been initially fooled by this, including me when I started playing.
