Some units of the SS-VT worked with the Wehrmacht during the take over of the Sudetenland, Austria, and Czechoslovakia, and took part in the invasion of Poland along with the campaign against the Allies in the West. From the regiments that made up the SS-VT came the Waffen-SS (or "Armed"-SS) Divisions that fought in all German theaters in World War II. Units making up the SS-VT were not known as the "Waffen-SS" until a speech by Adolf Hitler in July 1940.
