Gun Carrier Mark I
In service 1917 - 1918
The world first self-propelled gun: a tracked carrier that took a 60-pdr field gun across shell-torn ground.
Built byKitson and Co., Leeds

Development history
Devised to solve the problem that artillery could not follow a tank advance over cratered ground, the Gun Carrier held a 60-pdr gun or 6-inch howitzer that could be fired from the vehicle or unloaded for ground use. Forty-eight were built and they saw limited action in 1917, mostly at Ypres, before being reassigned to carrying supplies - a role in which they proved far more useful, one carrier moving the load of hundreds of men. It is the direct ancestor of every self-propelled gun that followed.
