Thanks for answering, Asai! You mean to say that, for instance, a two-star general leading three units will be seen on the battle map as THE GENERAL of the united army originating from different provinces and consequently the choice of a battle map will proceed from his larger stack, while a four-star general leading one unit from another province will become his subordinate? Would it be impolite to wonder whether you are guessing or are you sure of what you wrote?
