The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1945. It included the Heer (Army), Kriegsmarine (Navy), and Luftwaffe (Air Force). The Wehrmacht played a significant role in World War II, participating in various military campaigns across Europe and beyond. The organization was known for its military efficiency and tactics, but it was also involved in war crimes during the conflict. After Germany's defeat in 1945, the Wehrmacht was disbanded, and its legacy remains a complex topic in military history and discussions about the moral implications of warfare.
