Gas van

A gas van or gas wagon (Russian: душегубка, dushegubka, literally "soul killer"; German: Gaswagen) was a truck re-equipped as a mobile gas chamber. During World War II and the Holocaust, Nazi Germany developed and used gas vans on a large scale to kill inmates of asylums, Poles, Romani people, Jews, and prisoners in occupied Poland, Belarus, Yugoslavia, the Soviet Union, and other regions of German-occupied Europe. One case of gas vans used by Soviet NKVD during the Great Purge was documented.
