Before working on the next race, I'll make a short break to add something I wanted to do for a long time... BANNERS!
Generic units will not get banner, only heraldic units will get one. Usually one flag, to show their kingdom/tribe/clan, etc.
The high elves are a bit different: they get their kingdom flag, and a secondary flag specific to the unit type. They of course also keep their officer (but he has only one body guard left, the two others are now holding the flags)
See the preview below for Eataine.
