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
When the ROC was first issued with RAF style uniforms in 1941, the RAF was able to provide the majority of the uniform items but held insufficient stocks of RAF blue berets. However, at that time the Army held a surplus of black Royal Tank Regiment berets, therefore the ROC was initially issued with black berets, which remained part of the ROC uniform only until a manufacturer was able to produce the prescribed midnight blue berets, which then remained part of the ROC uniform throughout its history. There was a similar shortage of both Sergeant and Corporal stripes. However, there existed a large surplus of rank badges destined for the quasi-military "Royal Canadian (Volunteer) Storekeeper Corps" who served in UK dockside warehouses during the Second World War. These badges, displaying horizontal bars within a wreath of laurel leaves, were adopted for the ROC, with "Chief Storekeeper" becoming "Chief Observer" and "Leading Storekeeper" becoming "Leading Observer". The four bar rank of "Master Storekeeper" was discounted initially, but was again under consideration in 1990 as an RAF Warrant Officer equivalent rank styled "Master Observer"; intended to act as dedicated assistants to Crew, Group and NRC officers. However, the decision on whether to introduce the rank of Master Observer was overtaken by the standing down announcement. (The surplus rank badges destined for the Royal Canadian (Volunteer) Storekeeper Corps were also used by the United States' Civilian Technical Corps, who were based in the UK during the Second World War).
