The Panzer IV was a German medium tank used extensively during World War II. It had a distinctive angular design with a sloped armor plate that provided improved protection against enemy fire. The tank featured a powerful 75mm main gun, capable of penetrating most Allied tanks of the time. It had a crew of five, including a commander, gunner, loader, driver, and radio operator. With a top speed of around 40 km/h (25 mph), the Panzer IV was maneuverable on the battlefield, and its reliability and versatility made it one of the most widely produced tanks of the war.
