I’m intrigued by the reference to the AAOR.
As I’ve posted several times on the forum, it was at the TA Drill Hall on Watling Street when I worked for the Royal Engineers in 1944, when it was known to us as the Gun Operations Room (GOR), although that might not have been its official title – perhaps it was loosely used when the foreman told us there was a job at the ‘GOR’. However the photos are reminiscent of the plotting room there.
I only remember going to Fort Bridgewoods once, and it was then disused and I think we went to recover equipment.
Rochester City Archives record an army lorry being burnt out in there in 1940, and I remember being told by my father that its ATS driver lost her legs.
Is there any record of when the AAOR/GOR moved?
Is there any idea what the ‘Sub-Regional Control Centre was?
