A system of nomenclature developed to formally distinguish personnel based on their place of origin. Germanic units would have the "SS" prefix, while non-Germanic units were designated with the "Waffen" prefix to their names.[21] The formations with volunteers of Germanic background were officially named Freiwilligen (volunteer) (Scandinavians, Dutch, and Flemish), including ethnic Germans born outside the Reich known as Volksdeutsche, and their members were from satellite countries.
