Who were the German soldiers in charge of selection during the Holocaust?

The "SS," or Schutzstaffel, were the paramilitary organization under Adolf Hitler and played a pivotal role in the implementation of the Nazi regime's policies during the Holocaust. They were responsible for many of the atrocities committed against Jews and other targeted groups. Within the SS, there were specific units, such as the Einsatzgruppen, tasked with mass shootings and rounding up individuals for deportation to concentration camps. The SS was integral to the selection process of prisoners who were sent to death camps or forced labor camps, determining the fate of millions of people.

The other organizations, such as the Gestapo (the secret police), Wehrmacht (the regular German army), and Kripo (criminal police), had different functions and were not primarily entrusted with the systematic selection and deportation processes that the SS executed during the Holocaust. Thus, the SS stands out as the correct answer regarding the organization specifically assigned to make selection decisions during this tragic period in history.
