The Type 94 tankette (Kyūyon-shiki keisōkōsha, literally "94 type light armored car"; also known as TK, an abbreviation of Tokushu Keninsha, literally "special tractor") was a tankette used by the Imperial Japanese Army in the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in World War II. Although tankettes were often used as ammunition tractors, and general infantry support, they were designed for reconnaissance, and not for direct combat. The lightweight Type 94 proved effective in China as the Chinese National Revolutionary Army had only three tank battalions to oppose them, and those tank battalions were equipped only with some British export models and Italian CV-33 tankettes. As with nearly all tankettes built in the 1920s and 1930s, they had thin armor that could be penetrated by .50 caliber (12.7 mm) machine gun fire at range.
From the 1920s, the Imperial Japanese Army tested a variety of European light tanks, including several Renault FTs, and a decision was reached in 1929 to proceed with the domestic development of a new vehicle based largely on the Carden-Loyd Mk VI tankette design to address the deficiencies of wheeled armored cars.
The initial attempt resulted in the Type 92 Jyu-Sokosha for use by the cavalry. However, Japanese infantry commanders felt that a similar vehicle would be useful as the support vehicle for transport, scout and communications within the infantry divisions.
A tankette fad occurred in Europe in the early 1930s, which was led by United Kingdom's Carden-Loyd Mk VI tankette. The IJA ordered six samples from the UK, along with some French Renault UE Chenillette vehicles and field tested them. The IJA determined that the British and French machines were too small to be practical, and started planning for a larger version, the Tokushu Keninsha (TK, meaning "Special Tractor"). The Imperial Japanese Army also experimented with a variety of armored cars with limited success. The wheeled armored cars were not suitable for most operations in the puppet state of Manchukuo, due to the poor road conditions and severe winter climate.
