The German Panzer IV was a medium tank produced by Nazi Germany during World War II, commonly referred to as the Panzer IV. It was originally designed to support infantry and work in coordination with the Panzer III, which specialized in anti-tank missions. During the war, the Panzer IV was adapted into various specialized versions, including assault guns, self-propelled anti-tank guns, and bridge-laying tanks. Due to its reliable performance and versatility, German soldiers affectionately nicknamed it the ‘workhorse’.
