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. Please note that the list is as yet incomplete, with more units to be added.
The ASC MT Depot Companies
The ASC Mechanical Transport Depot Companies filled a variety of administrative, recruitment, induction, training and re-supply roles. The Base Depots were based in the United Kingdom or at the port of entry to a theatre of war. Advanced Depots were located further up the lines of communication.

The ASC MT Companies working as Divisional Supply Columns
Each Division of the army had a certain amount of motorised transport allocated to it, although not directly under its own command. The Divisional Supply Column Companies were responsible for the supply of goods, equipment and ammunition from the Divisional railhead to the Divisional Refilling Point and, if conditions allowed, to the dumps and stores of the forward units. Used, of course, where loads were heavy. A Company initially comprised 5 officers and 337 other ranks of the ASC, looking after 45 3-ton lorries, 16 30-cwt lorries, 7 motor cycles, 2 cars and 4 assorted trucks for the workshop and stores of the Supply Column itself. All Companies served in France unless otherwise mentioned.
