The original unit was officially known as "NSKK Gruppe Luftwaffe" and a second one was known as "NSKK Transportgruppe Todt". At Melun, the NSKK had its own driving school for French recruits and others from European countries. Before the "Schutzstaffel" (SS) began to openly recruit members into the Waffen-SS, Frenchmen used the NSKK as a "back-door" to get into the Waffen-SS to fight on the Eastern Front against the Soviet Union. Some French NSKK men were sent to the Eastern Front in a group known as "NSKK Einsatzgruppe Russland".
