Medium Mark A Whippet

The Medium Mark A Whippet was a medium tank employed by the British in World War I. Developed for fast mobile assaults, it was intended to complement the slower British heavy tanks by using its relative mobility and speed in exploiting any break in the enemy lines. Although the track design appears more "modern" than the British Tanks Mark I to V, it was directly derived from Little Willie, the first tank prototype (itself directly taken from the track design of the Holt tractor), and was unsprung. The crew compartment was a fixed, polygonal turret at the rear of the vehicle, and two engines of the type used in contemporary double-decker buses were in a forward compartment, driving one track each.
