Though take note that units can lose some veterancy if they take too many casualties because replacements are filled in by fresh recruits.
The more veterancy a unit has (displayed by chevrons on their unit card), the tougher the unit is. Experience is granted based upon how many kills a single unit has obtained during a battle. If you're lucky, one of your territories may have a special structure such as Buddhist monastary (grants additional morale) or a blacksmith (gives units stonger weapons or armor).īesides these structures, units can improve their skill from experience. You can construct an encampment which will grant specific buff to recruits in that single settlement.
You can't upgrade existing units outside of gaining experience, but what you can do is build certain structures within your settlement/territory that buff new recruits.
