The Army Service Corps was created after the amalgamation of the Commisariat and Transport Staff, and Corps in 1889. In 1918, they became the Royal Army Service Corps. In 1965 they were then amalgamated with the Transportation and Movement Control Service of the Royal Engineers, and became the Royal Corps of Transport. They now exist as the Royal Logisitics Corps, after amalgamation with the RAOC, RPC, ACC and postal and courier elements of the RE.
The Corps motto was: "HONI SOIT QUI MAL Y PENSE" which translated, means, "evil to him who evil thinks"
