Each GFP Gruppe consisted of a fifty-man unit until May 1942 when the entire command was restructured by SS-Brigadeführer Karl Oberg, the Higher SS and Police Leader (Höhere SS-und Polizeiführer, HSSPF) "Frankreich" (France). This reorganisation created the "Group 6/10" which contained the Kommando für Kapitalverbrechen (Capital crimes unit). It ran the infamous Balard shooting range at Issy-les-Moulineaux in the 15e arrondissement which was used to torture and execute 143 prisoners (though at the hands of the SS rather than the GFP).
