Einsatzgruppe

See also: Einsatzgruppen Case (NMT)

In general German military terminology, an Einsatzgruppe (plural Einsatzgruppen) is a temporary unit for a specific purpose, comparable to the English task force. Within the context of the Second World War and The Holocaust, they were mobile killing units that followed the armies invading the Soviet Union, ostensibly for rear area security and principally for killing Jews, Soviet officials, and other Nazi undesirables.

The genocidal groups, which killed approximately 2 million people, were organized in the summer of 1941, as part of the preparation for Operation Barbarossa. They all reported to the then head of the SS security organization, the RSHA, commanded by Reinhard Heydrich.

Organization

There were four main battalion-sized groups, and some smaller independent #insatzkommandos.

Group	Commander(s)	Attached to and strength	Area of operations
A	Franz Walter Stahlecker	Army Group North 990 men	From East Prussia across Lithuania, Latvia, and Estonia toward Leningrad (now St. Petersburg); Kovno, Riga, and Vilna.
B	Artur Nebe	Army Group Centre 665 men	From Warsaw across Belorussia toward Smolensk and Minsk, massacring Jews in Grodno, Minsk, Brest-Litovsk, Slonim, Gomel, and Mogilev, among other places.
C	Otto Rasch	Army Group South' 700 men	began operations from Krakow (Cracow) and fanned out across the western Ukraine toward Kharkov and Rostov-on-Don. Its personnel directed massacres in Lvov, Tarnopol, Zolochev, Kremenets, Kharkov, Zhitomir, and Kiev, where famously in two days in late September 1941 units of Einsatzgruppe detachment 4a massacred 33,771 Kiev Jews in the ravine at Babi Yar.
D	Otto Ohlendorf	11th Army 600 men	southern Ukraine and the Crimea, especially in Nikolayev, Kherson, Simferopol, Sevastopol, Feodosiya, and in the Krasnodar region.

Operations

Their primary means of killing was by shooting and burial in mass graves. Different commanders had different ideas on the method of shooting; some insisted on machine guns so no individual had clear responsibility for killing, while others insisted that every unit member shoot at individual victims, to bond them to the effort. With either method, there was a high degree of stress on the units, with rampant alcoholism.
