A "Panzer" refers to a German tank, particularly those used during World War II. The term comes from the German word for "armor." Panzer tanks were known for their powerful firepower, mobility, and effective armor, making them a significant part of the Wehrmacht and the Luftwaffe during the war. The most famous models include the Panzer III and Panzer IV, which were designed for different combat roles. The Tiger tank is another well-known variant, recognized for its heavy armor and firepower.
