The British Army was the most mechanised of all in the Great War when it came to using motor vehicles for transport. A large total of ASC Mechanical Transport Companies eventually existed, in the following categories. The ASC MT Companies allotted as Divisional Ammunition Parks. The MT Companies called Ammunition Parks operated dumps, or stores, of ammunition. This included the larger calibres of artillery shells which required special handling equipment, smaller shells, mortar rounds, grenades and small arms ammunition too. All saw service in France.
