Military enrolment in German-occupied Poland
After Nazi Germany's invasion of Poland in 1939, the Wehrmacht, or German armed forces, recruited members from Poland's 2.2% ethnic-German minority, but did not enlist ethnic Poles on racist grounds. When Germany began losing the war in 1943, the Wehrmacht forcibly conscripted ethnic Poles, who were commanded with racist policies against them.
