ルノー FT-17 軽戦車
After World War I, major powers around the world quickly adopted the revolutionary design of French Renault FT light tank. One of the most successful features on the Renault FT was a 360 degree rotating turret. While developing new single-turreted tanks more closely based on the Renault FT, many countries, including Japan, also experimented with the possibility of multi-turreted designs.
