Looking over my older source books, I see for (at least 5e) Mercenary info it'll include things like, "Mercenary Unit Rating" and a number 1 to 10, with 10 being noted as top dog by inference. But I was wondering, does anyone remember the sourcebook that originally described that err...descriptor? Was it ever officially hashed out or just a loose narrative 1-10 rating? Like it doesn't seem connected to "Professional Rating' of its member mercs and stuff.
