The Panzer III was armed with a 37mm Kwk 36 cannon and three MG-34s. The Mk III had a crew of five (Commander, Gunner, Loader, Driver, and Radio Operator) had a top speed of 40Km/h or 25Mph, and 30mm of armor all around.
In the Anime
In Izetta the Last Witch, the Mk III saw combat during the invasion of Livonia and the Invasion of Thermidor much likes its real world counterpart. It also saw combat in the opening rounds of the Invasion of Eylstadt where it proved effective in breaking through the Eylstadt trenches.
The Mk III was also used during the Battle of Coenenburg where it fought Eylstadt Renault FT-17s with no casualties, and breaking through the first defensive at Coenenburg before being halted by accurate artillery strikes. However the Mk IIIs had no effect when fighting Izetta, most were thrown into the air and chalked up as mobility kills.
