The SS-Begleitkommando was expanded and became known as the Führerbegleitkommando (Führer Escort Command; FBK).[8] By 1937, the unit had grown to 37 members.[9] The FBK continued under separate command and provided close, personal security for Hitler.[10] Additional members for the FBK were drawn from the Leibstandarte SS Adolf Hitler (LSSAH).[11] Hitler used them for guard duty, but also as orderlies, valets, waiters, and couriers.[11] While nominally under the control of Reichsführer-SS Heinrich Himmler, the FBK took their orders direct from Hitler, much to Himmler's frustration.[12] For administrative purposes, the FBK was under the control of the LSSAH.
