For administrative reasons, all concentration camp guards and administrative staff became full members of the Waffen-SS in 1942. The concentration camps were placed under the command of the SS-Wirtschafts-Verwaltungshauptamt (SS Main Economic and Administrative Office; WVHA) under Oswald Pohl.[189] Richard Glücks served as the Inspector of Concentration Camps, which in 1942 became office "D" under the WVHA.[190][191] Exploitation and extermination became a balancing act as the military situation deteriorated.
