The citizens of these countries who spoke German became highly valued because of their ability to communicate in Ukrainian, Russian, Polish and other languages of the occupied territories.[9] The training of non-Polish auxiliaries was arranged at Trawniki by SS-Hauptsturmführer Karl Streibel. Instructed by Globocnik to start recruiting behind the front lines of Operation Barbarossa, Streibel trained 5,082 mostly Ukrainian guards before the end of 1944.
