The Tank
Soon after the tank made it's first appearance at the Battle of the Somme in 1916, a lighter version was requested. This would be smaller, lighter and faster and could be used in the pursuit phase of a battle, although why after what occurred at the Somme pursuit came up at all is a mystery. However, using existing technology, the Whippet, as the light tank came to be known, was designed. Armed only with machine guns, it was faster than the Heavies in use at the time (a screaming 8 MPH), and had a crew of three instead of the eight needed to fight the Mk IV Heavy. The tank was very uncomfortable to ride in, only the driver having a seat, and the fighting compartment was behind the engine, so it got extremely hot and filled with exhaust fumes from the engine and powder fumes from the Hotchkiss MGs it carried. It was also un-reliable and could not be counted on to keep running for more than a few hours at a time before breaking down.
