The Einsatzgruppen were set up in order to kill Jews.
Yes, that was their function.
The main function of the Einsatzgruppen was to kill Jews behind German lines in the Soviet Union. They also killed Soviet guerrilla fighers and people who supported them, but in this second task they were supported by units of the regular army.
Einsatzgruppen translates to "task forces" or "deployment groups" in English. These were special paramilitary units in Nazi Germany responsible for carrying out mass killings of Jews, Gypsies, and other targets during World War II.
The German Einsatzgruppen (task groups) were execution squads that went in to places after the wehrmacht. The squads were composed of kriminal polizei, Gestapo, Waffen SS and SD men. These Einsatzgruppen were responsible for killing over one million jews.
About 1 million were shot by the Einsatzgruppen, but this was discontinued because it was obviously inefficient and was having a negative effect on the morale of the soldiers.
The special units to kill the Jews were the Einsatzgruppen (often referred to in English as 'mobile killing units').
There were mobile killing units (SD-Einsatzgruppen) which went into action behind German lines in the Soviet Union.
Adolf Hitler believed Germans, being inherently superior human beings, were threatened to their very existence by the inherently inferior Jews. The threat to the Sub-humans was so great that the only option was to exterminate them as though they were vermin.
Hitler and the Nazis most likely victimised the Jews because he thought the blonde-haired blue-eyed people and the Germans were the ultimate races. Hitler thought the Jews were nothing, less than people. He made it look like the concentration camps were fun, not evil.
You may be thinking of the Einsatzgruppen (mobile killing units), which carried out the early stages of the Holocaust.There was no Nazi police force devoted solely to 'dealing with the Jews'.
The Einsatzgruppen operated primarily during World War II, from 1939 to 1945. These mobile killing units were responsible for mass shootings, particularly of Jews, communists, and other groups deemed undesirable by the Nazis, especially in Eastern Europe following the invasion of the Soviet Union in 1941. Their activities contributed significantly to the Holocaust and resulted in the deaths of approximately 1.5 million people. The Einsatzgruppen were disbanded by the end of the war in 1945.
The 'official' purpose of the Einsatzgruppen was to combat guerrillas.
