ACAB

I'm remined of the Freikorps militia groups of Weimar Germany that would become the meat-and-potatoes recruits for the Sturmabteilung and early Schutzstaffel of the SS. On their own, The Freikorps served as law enforcement and peacekeepers, typically by disposing of town undesirables and locals in disfavor with the business class. In exchange, they got room and board and pretty much anything else they wanted (including the local womenfolk) since it was a really bad idea to deny them something they wanted.
