Comparing: Pz.Kpfw. II Luchs vs. A-20 vs. M5A1 Stuart

As compared to the Pz.Kpfw. II Ausf. C, the vehicle featured a new hull and turret, as well as a chassis with a staggered arrangement of roadwheels. The reconnaissance tank had strong characteristics, but only 131 vehicles of the L modification were built, after manufacture proved to be too expensive.

Development of the A-20 tank started at Kharkiv Factory No. 183 in December 1937. The project was a further development of the BT-7 tank and became a predecessor of the legendary T-34. Work on the vehicle was led by Mikhail Koshkin. On May 18, 1938, technical characteristics of the tank designated BT-20 were approved. Only a few experimental prototypes, with a wheeled caterpillar suspension, were built for training purposes.

The first tanks of the M5 series were produced in April 1942, and a new modification, the M5A1, was preferred over other variants. After the M24 Chaffee was developed, the M5A1 tanks were deemed obsolete and were exported to other countries, including China. A total of 100 tanks of this type were supplied to the Kuomintang. During the Civil War (1946–1949), many of these vehicles were captured by the PLA.
