Himmler set the SS and SD to work on developing additional anti-partisan tactics and launched a propaganda campaign.[176] Sometime in June 1943, Himmler issued the Bandenbekämpfung (bandit fighting) order, simultaneously announcing the existence of the Bandenkampfverbände (bandit fighting formations), with SS-Obergruppenführer Erich von dem Bach-Zelewski as its chief. Employing troops primarily from the SS police and Waffen-SS, the Bandenkampfverbände had four principal operational components: propaganda, centralized control and coordination of security operations, training of troops, and battle operations.[177] Once the Wehrmacht had secured territorial objectives, the Bandenkampfverbände first secured communications facilities, roads, railways, and waterways.
