Other formations included the Order Police battalions from Germany (Orpo) participating equally in the mass murder of Polish and Soviet Jews regardless of their age and sex,[4] including in the territories of the formerly Soviet-occupied Poland (see the Red Friday massacre), the Baltic states, and in the USSR proper.[5] Significant numbers of women and children were murdered behind all front lines not only by the Germans but also by the local Ukrainian and Lithuanian auxiliary forces.[6] The largest mass shooting of Soviet Jews took place on September 29, 1941, in the ravine of Babi Yar near Kiev, where 33,771 Jews of all ages were machine-gunned (Situation Report No. 101).[7]
