I guess having the followers use the same models as fighting bros wouldn't work because of "women and children", no way they are adding new randomized models just for that. Having them as town merchants that travel with you (which is how it looks like in the screen) is probably the right call. Still, the way of acquiring the drill sergeant is very awkward, you can use a level 3 beggar with an injury but not a level 10 retired soldier, appointing the drill sergeant should be done in the company window, with requirements something like at least level 8 and 50 resolve, the injury requirement sounds cool, but it's very awkward mechanically. You also lose whatever background and trait linked events you'd get from the brother that gets turned into the drill sergeant because technically he's left the company. Also the followers apparently only want money up-front and don't get paid and don't eat? The more I look at it, the less sense it makes.
