Something that really, really bugs me is the total lack of military specialization opportunities in BTS, especially since I'm a warmonger. What I mean is certain promotion given to all units in a Civilization, but not being determined by the civilization. So if I'm playing in a hilly region, I can make all future units I build have Guerrilla I. The way I think would be best for this is to change the way Great Generals work. Currently they just dump XP onto units you build in the city, which is fine, but what I want is for Great Generals to cause all units built from that city to gain a specific promotion determined when the Great General is placed in that city if eligible. So that leads me to my question, is there a mod that does this or something close to it, and if not, how difficult would it be for someone who's never modded before to do? It seems it would be quite hard since most modding focuses on adding Civilizations or units in different combinations. Also, how hard would it be to merge such a mod with BAT?
