Gas van

A gas van or gas wagon (Russian: душегубка, romanizeddushegubka, lit.'soul killer'; Serbian: душегупка, romanizeddušegupka; 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, Romani people, Jews, and prisoners in occupied Poland, Belarus, Serbia, the Soviet Union, and other regions of German-occupied Europe. There are several documented cases of gas vans used by Soviet NKVD during the Great Purge.
