Perhaps you should simply open all tables with mercenary in it. I find that oe of the best ways of learning modding is simply looking atother peoples mods. When I was first told this, I felt confused, all the tables just looked like gibberish back then. But, as I started learning modding, I can make sense of it all. If I seem patronizing,it isn't my intent; it's simply my experience then to now.
I suggest you look at Cataph's dogs of war mod for the border kingdoms; it adds regiment of renown to the three border factions another mod of his unlocks, so it should only contain the RoR stuff.
