Comparing: AC 1 Sentinel vs. SARL 42

Developed in 1941 under the program for Australian cruiser tanks. There were plans to produce 2,000 vehicles, but from 1942 through 1943, only 65 vehicles, with serial numbers from 8001 to 8065, were manufactured. In July 1943, it was decided to stop development and cancel the program. The vehicles never saw combat and were used only for training purposes. In 1946, the tanks were removed from service.

Developed by Hubert Clermont from 1940 through 1942, during the German occupation of France. Some elements of the SOMUA S35 medium tank and of the experimental G1R infantry tank were incorporated in the new vehicle. It was hoped that development would be continued after the liberation of the country. However, by 1944 the project was deemed outdated.
