The best tank of WW1. Was it th British Mark 1, French Renault FT-17, or the German A7 Sturmpanzerwagen?
Well... The A7V was just too big & cumbersome. The French Schneider and St. Chamond had crappy cross-country ability. The British series of tanks (with the Mk V being the best) were in my opinion he best 'heavy' tanks of WW1, being the best balance of firepower & mobility. The best light tank was definately the FT17, the design of which set the pattern for almost all tanks since. It was produced in 1,000's, was much copied, and was still in service (though hopelessly outclassed) in WW2.
