Fuller's ideas on mechanised warfare continued to be influential in the lead-up to the Second World War, ironically less with his countrymen than with the Nazis, notably Heinz Guderian who spent his own money to have Fuller's "Provisional Instructions for Tank and Armoured Car Training" translated. In the 1930s the German Army implemented tactics similar in many ways to Fuller's analysis, which became known as Blitzkrieg. Like Fuller, theorists of Blitzkrieg partly based their approach on the theory that areas of large enemy activity should be bypassed to be eventually surrounded and destroyed. Blitzkrieg-style tactics were used by several nations throughout the Second World War, predominantly by the Germans in the invasion of Poland (1939), Western Europe (1940), and the Soviet Union (1941). While Germany and to some degree the Western Allies adopted Blitzkrieg ideas, they were not much used by the Red Army, which developed its armored warfare doctrine based on deep operations, which were developed by Soviet military theorists Marshal M. N. Tukhachevsky et al. in the 1920s based on their experiences in the First World War and the Russian Civil War.
