Comparing: ST vz. 39 vs. SARL 42

V-8-H was a further development of the PS-II-b medium tank and the P-II-b light infantry tank. The vehicle underwent trials from the summer of 1937 through the spring of 1938. In the fall of 1938, additional trials were held. After all faults were removed, the tank saw service under the designation ST vz.39. The vehicle never entered mass production.

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 However, by 1944 the project was deemed outdated.
