Maybe one thing to have in mind for future titles is like in some nap mods made units.bmp have as unit image background the nation flag of the unit because in Marengo title like in others you could find units from one nation inside the army of other nation... here the problem is have as austrian rusian troops... if is not possible have them with diferent counters at least do the unit image background with nation flag.
Other good add could be add a symbol of unit class in the unit image... like add a NATO counter for infantry-cavalry-arty-engenier/sapper-supply.
I do here a fast edit to show this... i dont have the tools to cut the image of unit to paste behind it the flag... i add the small rusian flag from 2DSymbolsLg.bmp... and use NATO infantry symbol scaled from Volcanoman mods for Nap serie... here are great mods for Waterloo and other older titles and i think this help a lot improve the inmersion and dont miss important things.
