Final answer:
The German army had limited collaboration with the perpetrators of the Holocaust. (option 2)
Step-by-step explanation:
The German army had limited collaboration with the perpetrators of the Holocaust.
During the invasion of the Soviet Union in 1941, German armies were accompanied by squads called Einsatzgruppen, which were responsible for killing Jews, Gypsies, and other targeted groups. These mobile killing squads were aided by regular German army units and battalions of the Order Police. While many regular German soldiers were involved in the killings, it is important to note that not all German soldiers actively participated in the Holocaust. However, the level of collaboration varied among individuals and units within the German army.
