emmasim [6.3K]

Answer:

C. They carried out mass executions.

D. They were known as mobilized killing units.

E. They were used by Germany during the invasions of Poland and the Soviet Union.

Hence, the statements which best describe Einsatzgruppen are;

I. They carried out mass executions.

II. They were known as mobilized killing units.

III. They were used by Germany during the invasions of Poland and the Soviet Union.
