The type 97 Chi-Ha was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, the Battles of Khalkhin Gol against the Soviet Union, and the Second World War. It was the most widely produced Japanese medium tank of World War II. The Type 97 hull was of riveted construction with the engine in the rear compartment. The tank had a four-man crew including a driver, bow machine-gunner, and two men in the turret. In the forward compartment, the driver sat on the right, and bow gunner on the left. The commander’s cupola was placed atop the turret.
The Type 97 was equipped with a Type 97 57 mm main gun. The cannon was a short-barreled weapon with a relatively low muzzle velocity, but sufficient as the tank was intended primarily for infantry support. The main gun had no elevation gear, therefore, the gunner used his shoulder to elevate it.
The tank carried two 7.7 mm Type 97 machine guns, one on the front left of the hull and the other in a ball mount on the rear of the turret. The turret was capable of full 360-degree traverse, but the main gun was in a “semi-flexible mount” allowing a maximum 10-degree traverse independently of the turret. The tank weighed in at 14.3 tons and had top speed of 24MPH
