Vickers Medium Mk. ITier 1, Medium tank

In 1921, Vickers-Armstrong developed a project for the Vickers Light Tank. The 1923–1924 trials showed that the tank was ready for mass production. In 1924, the vehicle was renamed the Vickers Medium Tank Mk. I. The same year, a total of 30 vehicles were produced and entered service. Another 50 vehicles of the Mk. IA modification were manufactured later. The Vickers Medium Tank remained in service until 1938.
