Sonderkommando

Sonderkommandos were work units of Nazi death camp prisoners, composed almost entirely of Jews, who were forced, on threat of their own deaths, to aid with the disposal of gas chamber victims during The Holocaust. The death-camp Sonderkommando, who were always inmates, should not be confused with the SS-Sonderkommandos which were ad hoc units formed from various SS offices between 1938 through 1945.
