Ranks and insignia of the National Socialist Motor Corps
The ranks and insignia of the National Socialist Motor Corps (Nationalsozialistisches Kraftfahrkorps, abbr. NSKK) were a paramilitary rank system in Germany used between the years of 1931 and 1945. They were based closely on the ranks and insignia of the Sturmabteilung (SA), of which the NSKK was originally a part.
