Map included in Stahlecker's report from October 1941, summarizing murders committed by Einsatzgruppe A under his command: Estonia is "Judenfrei" (963 killed); Latvia (35,238 killed); Lithuania (138,421 killed); Russia (3,800 killed); Byelorussia (41,828 killed, see below)

The Stahlecker's map (top) outlined the Soviet Byelorussia not from before (pink), but after the Nazi-Soviet invasion of Poland (yellow). In the territories of Poland annexed by the Soviet Union the targets were Polish nationals

During World War II, the Nazi German Einsatzkommandos were a sub-group of five Einsatzgruppen mobile killing squads (term used by Holocaust historians) – up to 3,000 men total – usually composed of 500–1,000 functionaries of the SS and Gestapo, whose mission was to exterminate Jews, Polish intellectuals, Romani, Homosexuals, communists and the NKVD collaborators in the captured territories often far behind the advancing German front. After the outbreak of war with the Soviet Union known as Operation Barbarossa, the Red Army began to retreat so rapidly that the large Einsatzgruppen had to be split into dozens of smaller commandos (Einsatzkommandos), responsible for systematically killing Jews and, among others, alleged Soviet partisans behind the Wehrmacht lines. After the war several Einsatzkommando officers were tried, in the Einsatzgruppen trial, convicted of war crimes and hanged.

As a military term, the German Einsatzkommando (Operational Command) is roughly equivalent to the English task force and is still in use for German paramilitary organizations, such as SEK and Einsatzkommando Cobra.

Einsatzgruppen (German: special-ops units) were paramilitary groups originally formed in 1938 under the direction of Reinhard Heydrich – Chief of the SD, and Sicherheitspolizei (Security Police; SiPo). They were operated by the Schutzstaffel (SS). The first Einsatzgruppen of World War II were formed in the course of the 1939 invasion of Poland. Then following a Hitler-Himmler directive, the Einsatzgruppen were re-formed in anticipation of the 1941 invasion of the Soviet Union. The Einsatzgruppen were once again under the control of Reinhard Heydrich as Chief of the Reich Main Security Office (RSHA); and after his assassination, under the control of his successor, Ernst Kaltenbrunner.
