When the FBK unit was expanded, the additional officers and men were selected from the Leibstandarte SS Adolf Hitler (LSSAH).

The FBK accompanied Hitler on all his travels and was always present at the different Führerhauptquartiere (Führer Headquarters; FHQ) throughout World War II.

[1] From the twelve, a smaller eight-man team called the SS-Begleitkommando des Führers was chosen to protect Hitler as he travelled around Germany.

[6] The RSD and the SS-Begleitkommando cooperated with the Ordnungspolizei (uniformed order police), Gestapo, and other agencies to provide the inner security requirements, whereas outer protection was handled by general SS units.

[14] The FBK and RSD worked together for security and protection during trips and public events, but they operated as two groups and used separate vehicles.

[15] His FBK chauffeur Erich Kempka usually drove one of Hitler's black Mercedes-Benz cars from a fleet of six to eight that were stationed in Berlin, Munich and other places.

[17] In July 1938, upon Kempka's directive a fully armor-plated Mercedes was built and delivered in time for Hitler's 50th birthday of 20 April 1939.

[19] Guarding Hitler could require very long days, especially for the FBK members, who at times were on duty for twenty-four hours without rest.

[20] The FBK accompanied Hitler on all his travels and was always present at the different Führerhauptquartiere (Führer Headquarters; FHQ) in various parts of occupied Europe during World War II.

The FBK provided close security protection and would also be posted as guards in corridors leading to Hitler's office in places such as the Reich Chancellery.

This area housed the quarters of several Reich ministers, the HQ personnel, two messes, a communication centre, as well as the military barracks for the FBB.

Himmler wrote a strongly worded rebuke, after an incident that featured a drunken Gesche firing shots at a comrade.

[34][35] On 16 January 1945, following the failure of the Battle of the Bulge, Schädle accompanied Hitler and his entourage into the bunker complex under the Reich Chancellery garden in the central government sector of Berlin.

After descending the stairs into the lower section, RSD and FBK men were positioned in a guard room to check identity cards and briefcases, before personnel were allowed to pass into the corridor of the Führerbunker proper.

[40] During that time, most of the remaining FBK and RSD men had been withdrawn from the "exposed sentry posts" on the Chancellery roof and outside the Führerbunker entrances due to the shelling of the area by Soviet Red Army artillery.

[41] After Hitler's death, a briefing conference was held where prior orders were implemented that those who could do so were to break out from the centre government sector and join other German formations.
