Comparing: T18 vs. Universal Carrier 2-pdr vs. Renault FT AC

Development of this self-propelled gun on the basis of the M3 light tank started in October 1941. The first prototype passed trials in the spring of 1942, but the vehicle never saw mass production.

The Universal Carrier was developed during the interwar period and was the main armored personnel carrier used by British Commonwealth forces. A total of 90,000 vehicles were produced from 1937 through 1945. Versions of the Universal Carriers were used for transporting personnel and equipment, as machine gun platforms, and for reconnaissance purposes. In 1940, a variant with a 40-mm anti-tank gun was developed.

As the French Army's vast fleet of Renault FT tanks passed into obsolence, some efforts were made to upgrade the vehicles. One proposal was to convert them into tank destroyers, but the plan was never implemented.
