Misch was transferred to the FBK in early May 1940. As a junior member of Hitler's permanent bodyguard, Misch travelled with Hitler throughout the war. When not serving as bodyguards, Misch and the others in the unit served as telephone operators, couriers, orderlies, valets, and waiters. When on duty, the FBK members were the only armed men Hitler allowed to be near him. They never had to surrender their weapon and were never searched when they were with Hitler. It did cause Misch some concern that they were armed only with Walther PPK 7.65 pistols.
