British did not operate only infantry and cruiser tanks. Lack of production capacity meant the large scale adoption of US medium tanks. During the inter-war years, the French Army adopted three light tanks in the infantry tank role. These were the Hotchkiss H35, the Renault R35 and the FCM 36. All three had two–man crews and were similar to the Matilda I in terms of size, weight and armour. However, they were better armed, having 37mm guns as well as co-axial machine guns. In practice, although able to resist hits from other tanks and anti-tank guns, and designed for good, albeit slow, cross-country performance, the separation of tank functions into specialised areas such as infantry and cruiser types was not effective. Invariably the cruisers ended up meeting enemy tanks in combat, while the infantry tanks were the only ones present when a breakthrough was accomplished. The infantry tank idea faded as tank design progressed during the war. It was eventually replaced outright with the general acceptance of the 'universal tank' idea.
