The Royal Army Service Corps (RASC) was a corps of the British Army responsible for land, coastal and lake transport, air despatch, barracks administration, the Army Fire Service, staffing headquarters' units, supply of food, water, fuel and domestic materials such as clothing, furniture and stationery and the supply of technical and military equipment.

The corps was initially based at Horfield Barracks in Bristol, but in 1859 the 'Brigade Office' and Depot moved to Woolwich.

In 1869, there was a major reorganisation of army supply and transport capabilities: the commissaries of the Commissariat and the officers of the Military Train were amalgamated together with the officers of the Military Store Department to form what was called the Control Department under a Controller-in-Chief.

[3] Initially, the Commissariat and Transport Department remained part of the Department of Surveyor General of the Ordnance (in 1878 the Control Establishments Subdivision’s name was altered to the Commissariat and Transport Establishments Division under the supervision of a Commissary General).

The War Department Fleet was transferred to the Corps in 1891, and the ASC also absorbed some transport elements of the Royal Engineers.

Before the Second World War, RASC recruits were required to be at least 5 feet 2 inches tall and could enlist up to 30 years of age (or 35 for tradesmen in the Transport Branch).

All its supply functions (including the supply of vehicles, their care and preservation in storage and delivery), along with the staff clerks, were transferred to the Royal Army Ordnance Corps, leaving the new RCT solely responsible for transport and movements.

In 1993, the RCT and RAOC were merged to form the Royal Logistic Corps, the modern descendant of the ASC.
