Feldjägerkorps The Feldjägerkorps was a military police organization in the German Wehrmacht during World War II. It was formed on 27 November 1943 from distinguished veterans and Patrol Service personnel.

Staffelführer Staffelführer was one of the first paramilitary ranks used by the German "Schutzstaffel" (SS) in the early years of that group’s existence. The later SS rank of "Staffelführer" traces its origins to the First World War, where the title was used by commanding officers of the "Deutsches Heer"'s "Luftstreitkräfte" aircraft squadrons initially named as "Feldflieger Abteilung" as observation-only units in 1914, and during 1916, became known as "Staffeln".
