Comparing: AMX 40 vs. T-50 vs. M5A1 Stuart

Development was started in March 1940. Initially, the vehicle was to have a wheeled caterpillar propulsion system. The blueprint of the vehicle was created but in July 1940 work was discontinued.

Developed in October 1940. The design presented by Plant 174 was submitted for consideration. After successful trials in February and March 1941 the vehicle entered service.

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.
