The counterfactual starts with British investment in motorized fighting vehicles around 1900-1905. Japanese adoption could then put such vehicles into the Russo-Japanese War. Russian, French and German responses would give the idea a wider development history before 1914. The expectation is that roughly fifteen years of competition would produce better vehicles than those available at the start of the First World War. No specific battle result or final vehicle design is predicted.
