Lack of precise documentation does not allow to specify precisely which elements of the above were involved in the Wola killing. It is also possible that some units of the other assault group that operated in the Wola area (Angriffsgruppe Reck) were taking active part in the events, as they also consisted of police/gendarmerie and special assignment units (Hptm. Kirchhubel's Warschau Polizei Kompanie, Hptm. Fersemann's Polizei Wachtkompanie, platoon of SS-Röntgen MG Kompanie from Posen (Poznan), but also SS Grenadiere of SS-Schule Treskau and Azerbaijani 7.Komp/II Bt. Bergmann).
