query: What was the role of the Serbian Volunteer Corps during World War II?
answer: The Serbian Volunteer Corps (SDK) was a paramilitary branch of the fascist organization Zbor that collaborated with Nazi Germany in occupied Serbia during World War II.  Initially formed to combat communist Partisans and royalist Chetniks, it grew significantly and participated in numerous operations alongside German forces against these groups.  Following the Red Army's advance into Serbia, the SDK retreated with the Germans, eventually being incorporated into the Waffen-SS.  The remaining members surrendered to the British in 1945, but most were later returned to Yugoslavia and executed for treason.
