The idea of a 'fast tank', based on the Christie suspension, came to the British only in the mid-1930s. The various trials of experimental mechanized forces of the 1920s and early 1930s had led info the development of three distinct types of lank - the 'infantry tank' to support infantry in the attack (slow, lhighlly armed, but heavily armored), the cruiser tank' (faster, more lightly armored, fitted with a gun suitable for taking on enemy tanks), and the 'light tank' (last but hightly armed and armored, for reconatssance).
