Royal Hong Kong Auxiliary Air Force 1949–1993 Airfield Defence Force Flights 1986–1993 RAF Brampton RAF High Wycombe RAF St Athan and RAF Lyneham – members of the Defence Force served the Royal Air Force at Lyneham for eight years between 1986 and 1994. A localised recruiting drive began in the summer of 1986. At the time, the Cold War was still in progress and the Soviet Union was regarded as a considerable threat to UK bases. So a plan was created to develop a system of ground defence for the vital bases without extending regular forces and for a modest outlay. As the Royal Auxiliary Air Force had already been revived in 1979 to provide aeromedical evacuation services, air movements and Regiment Field squadrons, it was planned to set up the Defence Force flights and task one of them to protect RAF Lyneham, home of the UK's air transport squadrons. Volunteers between 18 and 50 were sought within a radius of 50 miles of Lyneham and the first training flight came into being in late 1986, under the command of Flt Lt Bryan Tovey, a retired RAF Squadron Leader. Within five years, over 100 volunteers attended Lyneham on Wednesday evenings and weekends, trained in all the essential field combat skills such as weapons handling and live-firing practice, fieldcraft, perimeter defence, fighting in built up areas, reconnaissance, intelligence-gathering, fire-fighting and rescue techniques plus nuclear, biological and chemical monitoring. Battlefield skills were regularly tested at military training areas and such was the reputation built-up by the Lyneham Defence Force that their personnel were once used to assist regular special forces in training scenarios.
