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.
Royal Observer Corps
As a result of their role during the Battle of Britain, in April 1941 the Observer Corps was granted the title "Royal" by King George VI, and the "Royal Observer Corps" (ROC) became a uniformed civil defence organisation administered by RAF Fighter Command. Also during that same year, in a change from the policy of the Observer Corps, the ROC undertook to recruit women personnel for the first time. Initially, the only uniforms provided were RAF overalls, ("boiler suits"), with an ROC breast badge, commonly referred to as the "soup plate" because of its shape and size. Standard issue RAF No.2 Battledress uniforms were issued in a rolling programme over the next two years. For the remainder of the war, the ROC would provide an essential part of Great Britain's air defences.
