Operational instruments of the Royal Observer Corps
The Royal Observer Corps (ROC) was a civil defence organisation operating in the United Kingdom between 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; a serving RAF Air Commodore.
Volunteer Air Observers Corps (Australia)
The Volunteer Air Observers Corps (VAOC) was an Australian air defence organisation of World War II. The VAOC was formed on 31 December 1941 to support the Royal Australian Air Force by sighting and observing aircraft over Australia. The VAOC swiftly established observation posts across Australia and provided information to the RAAF's regional air control posts. As the threat to Australia declined the VAOC's role was expanded to include coast watching, assisting air traffic control and weather reporting. The VAOC was staffed by civilian volunteers and reached a peak strength of 24,000 personnel and 2,656 observation posts in 1944. After the end of the war the VAOC was reduced to a cadre in December 1945 and was disbanded on 10 April 1946. The VAOC was similar to the British Royal Observer Corps.
