奉系軍閥的FT-17 - 中國歷史圖片，維基媒體

The Renault FT (Fusilier Tank) was a French light tank that was introduced during World War I. It was one of the first tanks to feature a fully rotating turret, which allowed the tank to engage targets in any direction. The Renault FT was also the first tank to be mass-produced, with over 3,800 units built during the war. The tank had a crew of two and was armed with either a 37mm cannon or a machine gun. It had a top speed of 7 miles per hour and could cross trenches up to 6 feet wide. The Renault FT was used by several countries during and after World War I, including France, the United States, Poland, and Yugoslavia. The Renault FT was considered a revolutionary design at the time, and its influence can still be seen in modern tanks today. Its success on the battlefield helped pave the way for the development of armored warfare in the 20th century.
