SS-Verfügungstruppe (SS-VT) (English: SS Dispositional Troops) was formed in 1934 as combat troops for the Nazi Party (NSDAP). On 17 August 1938 Adolf Hitler decreed that the SS-VT was neither a part of the police nor the German Wehrmacht, but military-trained men at the disposal of the Führer. At the time of war, the SS-VT were to be placed at the disposal of the army. The SS-VT were involved in the German invasion of Poland in September 1939. By 1940 these military SS units had become the nucleus of the Waffen-SS.
