The Panzer III was a medium tank developed by Germany in the late 1930s and widely used during World War II. It featured a 50 mm KwK 38 L/42 or later a 50 mm KwK 39 L/60 main gun, providing effective firepower against early war tanks. With a top speed of around 40 km/h and armor thickness up to 70 mm in later versions, it balanced mobility and protection, playing a key role in the early blitzkrieg campaigns.
