Einsatzgruppen (German for "task forces", "deployment groups"; singular Einsatzgruppe; official full name Einsatzgruppen der Sicherheitspolizei und des SD) were Schutzstaffel (SS) paramilitary death squads of Nazi Germany that were responsible for mass killings, primarily by shooting, during World War II. The Einsatzgruppen were involved in the murder of much of the intelligentsia and cultural elite of Poland, and had an integral role in the implementation of the Final Solution of the Jewish question (Die Endlösung der Judenfrage) in territories conquered by Nazi Germany. Almost all of the people they killed were civilians, beginning with the intelligentsia and swiftly progressing to Soviet political commissars, Jews, and Gypsies throughout Eastern Europe.
