A VoMi unit, "Sonderkommando R (Russland)", institutional successor to "Einsatzgruppe D" in the Transnistria area, carried out numerous massacres of Jews during the first half of 1942. The victims were deportees from Rumanian-controlled territory, it being Marshal Ion Antonescu's policy to racially "cleanse" the Rumanian nation. His preferred technique was to expel them to German-controlled territory and have the responsible SS/ Police units exterminate them. Many of these Jews were passed back and forth for weeks before a mix of Sk-R units and ethnic German Selbstschutz militia killed them.
