Reich Security Main Office Heydrich held the title of
Chef der Sicherheitspolizei und des SD (Chief of the Security Police and SD) until 27 September 1939, when he became chief of the newly established Reich Security Main Office (RSHA). From that point forward, the RSHA was in charge of SS security services. It had under its command the SD, Kripo, and Gestapo, as well as several offices to handle finance, administration, and supply.
Heinrich Müller, who had been chief of operations for the Gestapo, was appointed Gestapo chief at this time.
Arthur Nebe was chief of the Kripo, and the two branches of SD were commanded by a series of SS officers, including
Otto Ohlendorf and
Walter Schellenberg. The SD was considered an elite branch of the SS, and its members were better educated and typically more ambitious than those within the ranks of the
Allgemeine SS. Members of the SD were specially trained in criminology, intelligence, and counterintelligence. They also gained a reputation for ruthlessness and unwavering commitment to Nazi ideology. Heydrich was attacked in Prague on 27 May 1942 by a British-trained team of Czech and Slovak soldiers who had been sent by the
Czechoslovak government-in-exile to assassinate him in
Operation Anthropoid. He died from his injuries a week later. Himmler ran the RSHA personally until 30 January 1943, when Heydrich's positions were taken over by Kaltenbrunner.
SS-Sonderkommandos Beginning in 1938 and throughout World War II, the SS enacted a procedure where offices and units of the SS could form smaller sub-units, known as
SS-Sonderkommandos, to carry out special tasks, including large-scale murder operations. The use of
SS-Sonderkommandos was widespread. According to former SS-
Sturmbannführer Wilhelm Höttl, not even the SS leadership knew how many
SS-Sonderkommandos were constantly being formed, disbanded, and reformed for various tasks, especially on the Eastern Front. An
SS-Sonderkommando unit led by SS-
Sturmbannführer Herbert Lange murdered 1,201 psychiatric patients at the
Tiegenhof psychiatric hospital in the
Free City of Danzig, 1,100 patients in
Owińska, 2,750 patients at
Kościan, and 1,558 patients at
Działdowo, as well as hundreds of Poles at
Fort VII, where the mobile gas van and gassing bunker were developed. In 1941–42,
SS-Sonderkommando Lange set up and managed the first extermination camp, at
Chełmno, where 152,000 Jews were killed using gas vans. After the
Battle of Stalingrad ended in February 1943, Himmler realised that Germany would likely lose the war and ordered the formation of
Sonderkommando 1005, a special task force under SS-
Standartenführer Paul Blobel. The unit's assignment was to visit mass graves on the Eastern Front to exhume bodies and burn them in an attempt to cover up the genocide. The task remained unfinished at the end of the war, and many mass graves remain unmarked and unexcavated. The
Eichmann Sonderkommando was a task force headed by
Adolf Eichmann that arrived in Budapest on 19 March 1944, the same day that
Axis forces invaded Hungary. Their task was to take a direct role in the deportation of Hungarian Jews to Auschwitz. The
SS-Sonderkommandos enlisted the aid of antisemitic elements from the Hungarian gendarmerie and pro-German administrators from within the Hungarian Interior Ministry. Round-ups began on 16 April, and from 14 May, four trains of 3,000 Jews per day left Hungary and travelled to the camp at Auschwitz II-Birkenau, arriving along a newly built spur line that terminated a few hundred metres from the gas chambers. Between 10 and 25 per cent of the people on each train were chosen as forced labourers; the rest were killed within hours of arrival. Under international pressure, the Hungarian government halted deportations on 6 July 1944, by which time over 437,000 of Hungary's 725,000 Jews had been murdered.
Einsatzgruppen , Ukraine, 1941; a teenage boy is brought to view his dead family before being shot himself The
Einsatzgruppen had its origins in the ad hoc
Einsatzkommando formed by Heydrich following the
Anschluss in Austria in March 1938. Two units of
Einsatzgruppen were stationed in the Sudetenland in October 1938. When military action turned out not to be necessary because of the
Munich Agreement, the
Einsatzgruppen were assigned to confiscate government papers and police documents. They secured government buildings, questioned senior civil servants, and arrested as many as 10,000 Czech communists and German citizens. The
Einsatzgruppen also followed
Wehrmacht troops and killed potential partisans. Similar groups were used in 1939 for the
occupation of Czechoslovakia. Hitler felt that the planned extermination of the Jews was too difficult and important to be entrusted to the military. In 1941 the
Einsatzgruppen were sent into the Soviet Union to begin large-scale genocide of Jews, Romani people, and communists. Historian
Raul Hilberg estimates that between 1941 and 1945 the
Einsatzgruppen and related agencies murdered more than two million people, including 1.3 million Jews. The largest mass shooting perpetrated by the
Einsatzgruppen was at
Babi Yar outside
Kiev, where 33,771 Jews were massacred in a single operation on 29–30 September 1941. In the
Rumbula massacre (November–December 1941), 25,000 victims from the
Riga ghetto were murdered. In another set of mass shootings (December 1941 – January 1942), the
Einsatzgruppe massacred over 10,000 Jews at
Drobytsky Yar in
Kharkov. The last
Einsatzgruppen were disbanded in mid-1944 (although some continued to exist on paper until 1945) due to the German retreat on both fronts and the consequent inability to continue extermination activities. Former
Einsatzgruppen members were either assigned duties in the
Waffen-SS or concentration camps. Twenty-four
Einsatzgruppen commanders were tried for war crimes following the war.
SS Court Main Office The
SS Court Main Office (
Hauptamt SS-Gericht) was an internal legal system for conducting investigations, trials, and punishment of the SS and police. It had more than 600 lawyers on staff in the main offices in Berlin and Munich. Proceedings were conducted at 38 regional SS courts throughout Germany. It was the only authority authorised to try SS personnel, except for SS members who were on active duty in the
Wehrmacht (in such cases, the SS member in question was tried by a standard military tribunal). Its creation placed the SS beyond the reach of civilian legal authority. Himmler personally intervened as he saw fit regarding convictions and punishment. Historian
Karl Dietrich Bracher describes this court system as one factor in the creation of the Nazi totalitarian police state, as it removed objective legal procedures, rendering citizens defenceless against the "summary justice of the SS terror."
SS Cavalry Shortly after Hitler seized power in 1933, most horse riding associations were taken over by the SA and SS. Members received combat training to serve in the
Reiter-SS (SS Cavalry Corps). The first SS cavalry regiment, designated
SS-Totenkopf Reitstandarte 1, was formed in September 1939. Commanded by then SS-
Standartenführer Hermann Fegelein, the unit was assigned to Poland, where they took part in the extermination of Polish intelligentsia. Additional squadrons were added in May 1940, for a total of fourteen. The unit was split into two regiments in December 1939, with Fegelein in charge of both. By March 1941 their strength was 3,500 men. In July 1941, they were assigned to the
Pripyat Marshes massacres, tasked with rounding up and exterminating Jews and partisans in the
Pripyat swamps. The two regiments were amalgamated into the
SS Cavalry Brigade on 31 July, twelve days after the operation started. Fegelein's final report, dated 18 September 1941, states that they killed 14,178 Jews, 1,001 partisans, and 699 Red Army soldiers, with 830 prisoners taken. Historian Henning Pieper estimates the actual number of Jews killed was closer to 23,700. The SS Cavalry Brigade took serious losses in November 1941 in the
Battle of Moscow, with casualties of up to 60 per cent in some squadrons. Fegelein was appointed as commander of the
8th SS Cavalry Division "Florian Geyer" on 20 April 1943. This unit saw service in the Soviet Union in attacks on partisans and civilians. In addition, SS Cavalry regiments served in Croatia and Hungary.
SS Medical Corps on the
Judenrampe (Jewish ramp) after disembarking from the
transport trains. Photo from the
Auschwitz Album, May 1944 The SS Medical Corps were initially known as the
Sanitätsstaffel (sanitary units). After 1931, the SS formed the headquarters office
Amt V as the central office for SS medical units. An SS medical academy was established in Berlin in 1938 to train
Waffen-SS physicians. SS medical personnel did not often provide actual medical care; their primary responsibility was medicalised genocide. At Auschwitz, about three quarters of new arrivals, including almost all children, women with small children, all the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be completely fit were killed within hours of arrival. In their role as
Desinfektoren (disinfectors), SS doctors also made selections among existing prisoners as to their fitness to work and supervised the murder of those deemed unfit. Inmates in deteriorating health were examined by SS doctors, who decided whether or not they would be able to recover in less than two weeks. Those too ill or injured to recover in that time frame were killed. At Auschwitz, the actual delivery of gas to the victims was always handled by the SS, on the order of the supervising SS doctor. Many of the SS doctors also conducted inhumane medical experiments on camp prisoners. The most well-known SS doctor,
Josef Mengele, served as a medical officer at Auschwitz under the command of
Eduard Wirths of the camp's medical corps. Mengele undertook selections even when he was not assigned to do so in the hope of finding subjects for his experiments. He was particularly interested in locating sets of twins. In contrast to most of the doctors, who viewed undertaking selections as one of their most stressful and horrible duties, Mengele undertook the task with a flamboyant air, often smiling or whistling a tune. After the war, many SS doctors were charged with war crimes for their medical experiments and for their role in gas chamber selections.
Other SS units Ahnenerbe The
Ahnenerbe (Ancestral Heritage Organisation) was founded in 1935 by Himmler and became part of the SS in 1939. It was an umbrella agency for more than fifty organisations tasked with studying German racial identity and ancient Germanic traditions and language. The agency sponsored archaeological expeditions in Germany, Scandinavia, the Middle East, Tibet, and elsewhere to search for evidence of Aryan roots, influence, and superiority. Further planned expeditions were postponed indefinitely at the start of the war.
SS-Helferinnenkorps The
SS-Helferinnenkorps () were female auxiliary members of the
Waffen-SS. The organization was created to free men for combat by assigning women to non-combat support roles such as administration, communications, and logistics. Established in 1942 under the direction of
Ernst Sachs, it was Himmler's intention to create a "sister organisation to the Schutzstaffel". Around 10,000 women served in the
SS-Helferinnenkorps, in addition to 15,000 police auxiliaries. They were present in diverse areas, from the offices of the
Reich Security Main Office in Berlin to the
concentration camps. In 1942, Himmler set up the
Reichsschule für SS Helferinnen (Reich School for SS Helpers) in
Oberehnheim to train women in communications, again to free up men for combat roles. Himmler intended to replace all female civilian employees in his service with
SS-Helferinnen members, as they were selected and trained according to Nazi ideology. The school was closed on 22 November 1944 due to the Allied advance.
SS-Gefolge The
SS-Gefolge () served as civilian employees without formal SS membership or combat training. They were affiliated with the
Waffen-SS. Their roles were primarily administrative, working as guards and auxiliaries in concentration camps, with 3,517 female guards (comprising 10% of the total in January 1945), including around 200 at Auschwitz. Often trained at
Ravensbrück, they took loyalty oaths and enforced camp policies tied to
The Holocaust,
sterilization, and
euthanasia, and supervised prisoners, aiding
Nazi racial policies. ==Foreign legions and volunteers==
