The Type 97 medium tank Chi-Ha was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and the Second World War. It was the most widely-produced Japanese medium tank of WWII, with about 26mm thick armor on its turret sides, and 33mm on its gun shield, considered average protection in the 1930s.
The Chi-Ha was the most widely available medium tank to the Japanese Army when the Race invaded in mid 1942. Hopelessly outmatched by the Race Landcruisers, the Chi-Ha was thrown into the fight because it was all the Japanese had. The Chi-Ha was not well respected by landcriuser crews and earned the dubious nickname "One-Shot Firestarters," because they were guaranteed to brew up with only one hit.
