During the late 1930s, the power of the SS-HA continued to grow becoming the largest and most powerful office of the SS, managing nearly all aspects of the paramilitary organization. This included the SS officer schools (SS-Junker Schools), physical training, communication, SS garrisons, logistics and support. Shortly after the outbreak of World War II in Europe, the "SS-Verfügungstruppe" expanded rapidly becoming the Waffen-SS in 1940. By this time, the office of the "SS-Hauptamt" could no longer administer the entire SS organization. As a result, the SS-HA was downsized losing much of its pre-war power to the "SS Führungshauptamt" (SS Leading Main Office; SS-FHA) and the main offices of the "Allgemeine-SS", such as the Reich Main Security Office.
