One thing I'd like to know more about is just what everyone did in an HAA battery. Among my fathers possessions is an address book listing men from 164 battery of the 59th (The Essex Regt) HAA. This book is divided into 3 sections listing 15 officers, 300 other ranks and 81 that joined in a Garrison Police role after the cessation of hostilities. I'm guessing that all those listed were still alive when this was published, so ignoring the 3rd category, there were a total of 315 men employed in this battery during WW2. 164 Battery had 2 'troops' ("Troop A" & "Troop B") each with 4 guns (i.e. 8 guns in total). Each gun crew generally consisted of 9 men, although I have one crew photo that shows 10 men. But lets say there were 8 x 9 = 72 men involved in firing the guns, that leaves 228. There were 5 men operating each predictor, so that accounts for another 8 x 5 = 40, leaving 188. There was a gun position officer (GPO) and assistant (GPOac), that's another 16. Then there was the gun operations room (GOR), the Royal Electrical & Mechanical engineers (REME), the Royal Army Service Corps (RASC), and Signals/Telecomms Section. Dad was steadily promoted from gunner to sergeant, and his war record shows he did training courses in mechanics, so I guess he stopped firing guns well before the end of hostilities. So I wonder if there was a typical sergeant's role in the HAA. This photo probably shows all the sergeants in just Troop "B" sitting outside their Sergeants Mess. Dad is on the left, partially blocking the "Holiday Inn" sign.
