Although some proponents of mobile warfare, such as J. F. C. Fuller, advocated building "tank fleets", other, such as Heinz Guderian in Germany, Adna R. Chaffee Jr. in the United States, and Mikhail Tukhachevsky in the Soviet Union, recognized that tank units required close support from infantry and other arms and that such supporting arms needed to maintain the same pace as the tanks.
