The Führer Grenadier Brigade (formerly Führer Grenadier Battalion later Führer Grenadier Division) was an élite German Army combat unit which saw action during World War II.
 The Führer Grenadier Brigade is sometimes mistakenly perceived as being a part of the Waffen-SS, whereas it was actually an Army unit and technically assigned to the Großdeutschland Division.
 This misconception comes from its original duty of guarding Adolf Hitler's East Prussian Wolfsschanze Headquarters, a task which sounded similar to the original one of Waffen-SS 1.
 Panzer Division "Leibstandarte SS Adolf Hitler", which in turn stemmed from the Führer's original bodyguard corps.
 Fighting on both the Eastern and Western Fronts, the brigade surrendered to U.S. forces in Austria in 1945.
Sudetendeutsches Freikorps (Sudeten German Free Corps, also known as the Freikorps Sudetenland, Freikorps Henlein and Sudetendeutsche Legion) was a paramilitary Nazi organization founded on 17 September 1938 in Germany on direct order of Adolf Hitler.
 The organization was composed mainly of ethnic German citizens of Czechoslovakia with pro-Nazi sympathies who were sheltered, trained and equipped by German authorities and who were conducting cross border terrorist operations into Czechoslovak territory from 1938 to 1939.
 They played an important part in Hitler's successful effort to occupy Czechoslovakia and annex the region known as Sudetenland into the Third Reich under Nazi Germany.
The Bug Star, more formerly known as the Bug Star of the Schutztruppe Bug was a paramilitary award of the German Freikorps which was issued in the 1920s.
 Awarded under the authority of local Freikorps commander Major Kobe von Keppenfels, the Bug Star recognized various achievements to members of the local Freikorps.
 The Freikorps itself was composed mostly of World War I veterans who had served in the Kurland and Lithuania.
Gertraud "Traudl" Junge (née Humps; 16 March 1920 – 10 February 2002) worked as Adolf Hitler's last private secretary from December 1942 to April 1945.
 After typing out Hitler's will, she remained in the Berlin "Führerbunker" until his death.
 Following her arrest and imprisonment in June 1945, both the Soviet and the American militaries interrogated her.
 Later, in post-war West Germany, she worked as a secretary.
 In her old age she decided to publish her memoirs, claiming ignorance of the Nazi atrocities during the war, but blaming herself for missing opportunities to investigate reports about them.
 Her story, based partly on her book, "Until the Final Hour", formed a part of several dramatizations, in particular the 2004 German film "Downfall" about Hitler's final ten days.
The Mind of Adolf Hitler: The Secret Wartime Report, published in 1972 by Basic Books, is based on a World War II report by psychoanalyst Walter C. Langer which probed the psychology of Adolf Hitler from the available information.
 The original report was prepared for the Office of Strategic Services (OSS) and submitted in late 1943 or early 1944; it is officially entitled "A Psychological Analysis of Adolph Hitler: His Life and Legend".
 The report is one of two psychoanalytic reports prepared for the OSS during the war in an attempt to assess Hitler's personality; the other is "Analysis of the Personality of Adolph Hitler" by the psychologist Henry A. Murray who also contributed to Langer's report.
 The report eventually became 1000 pages long.
Hans Hermann Junge (11 February 1914 – 13 August 1944) born in Preetz / Holstein was a German SS officer who served as aide-de-camp and valet to Adolf Hitler.
 He was married to Traudl Junge, Hitler's last private secretary.
 He was killed in combat during World War II in August 1944.
The last will and testament of Adolf Hitler was prompted by Hitler receiving a telegram from "Reichsmarschall" Hermann Göring asking for confirmation of Göring's succession, combined with news of Heinrich Himmler's attempted negotiations of surrender with the western Allies, and reports that Red Army troops were within a block or two of the Reich Chancellery.
 It was dictated by Adolf Hitler to his secretary Traudl Junge in his Berlin "Führerbunker" on 29 April 1945, the day he and Eva Braun married.
 They committed suicide the following day, 30 April, two days before the surrender of Berlin to the Soviets on 2 May, and just over a week before the end of World War II in Europe on 8 May.
 It consisted of two separate documents, a will and a political testament.
The Freikorps Sauerland (Free Corps of Sauerland), was a paramilitary association created by Gauleiter Albert Hoffmann in September 1944.
 In October, the Freikorps was officially established, and accepted by the Party Chancellery of Nazi Germany, where Martin Bormann, head of the Volkssturm associated the Freikorps to his services, as they often completed tasks, missions, etc. with them in the final months of the war.
 Hoffmann saw the Freikorps Sauerland as an "elite unit" in his Gau Westfalen-Süd campaigns against Allied Forces (notably, this is also where Albert Hoffmann had served as the Gauleiter before war had broken out).
Martin Bormann (17 June 1900 – 2 May 1945) was a prominent official in Nazi Germany as head of the Nazi Party Chancellery.
 He gained immense power within the Third Reich by using his position as Adolf Hitler's private secretary to control the flow of information and access to Hitler.
The military career of Adolf Hitler can be divided into two distinct portions of Adolf Hitler's life.
 Mainly, the period during World War I when Hitler served as a "Gefreiter" (lance corporal) in the Bavarian Army, and the era of World War II when Hitler served as the Supreme Commander-in-Chief of the Wehrmacht (German Armed Forces) through his position as Führer of Nazi Germany.
