query: When was the Royal Observer Corps established?
passage: Royal Observer Corps
The Royal Observer Corps (ROC) was a civil defence organisation intended for the visual detection, identification, tracking and reporting of aircraft over Great Britain. It operated in the United Kingdom between 29 October 1925 and 31 December 1995, when the Corps' civilian volunteers were stood down. (ROC headquarters staff at RAF Bentley Priory stood down on 31 March 1996). Composed mainly of civilian spare-time volunteers, ROC personnel wore a Royal Air Force (RAF) style uniform and latterly came under the administrative control of RAF Strike Command and the operational control of the Home Office. Civilian volunteers were trained and administered by a small cadre of professional full-time officers under the command of the Commandant Royal Observer Corps; latterly a serving RAF Air Commodore.
passage: Royal Observer Corps Medal
In July 1961 the Commandant ROC Air Commodore Wight-Boycott presented a Royal Observer Corps Medal to the Battle of Britain Class locomotive no.34050 "Royal Observer Corps", which had commenced service with the Southern Railway company in December 1946; the ceremony taking place at Waterloo station. The medal was mounted in a glass fronted cabinet in the driver's cab and the locomotive's side was repainted with a representation of the medal and its ribbon. These were displayed until the engine was retired from service and scrapped in the late 1960s. However, the original nameplate and front badge were recovered and displayed in the entrance hall of RAF Bentley Priory, (HQ ROC), until 1996 when they were transferred to the RAF Museum, Hendon.
