Mechanization of ground forces first came about during the 1st World War with the introduction of an armoured tracked vehicle fielding a large bore cannon, by England. This vehicle was dubbed "Tank" by Winston Churchill, and the innovation has altered the conduct of warfare to this day. During the second conflict, the mechanization of Infantry was perfected by the Germans and brought about the name Blitzkrieg. During that conflict over 3 million military vehicles were produced, and even thought the tank had considerable advantages, the need for a method of having the Infantry keep pace with them became a necessity.
