That maybe too, but imo, there should be basic generic units like "Infantry", "Marines" etc., just because there always might be someone who RPs armed forces which would neither be mercenaries nor soldiers belonging to a House. Also, it would be too much work for the modders to create such soldier commodities for every faction; I think it would be much easier to just create custom ones for the major factions (Houses including unlawful ones, plus Wilde and probably Nomads) and generic ones for everyone else.
