Surnames/tags: Bomber Command Group
This was the British structure. There were also Fighter Command and Bomber Command The next level down was Squadron but complicated because there were about 8 National Air Forces under Bomber Command Groups
These may have existed pre and post WW2 as not being under direct British control eg 452 Squadron Royal Australian Air Force was a National Unit, then transferred to Fighter Command then back to Australian control.
Even the USAAF was under Bomber Command until it was fully set up but worked closely with RAF Bomber Command "Wikipedia - USSTAF had started as the Eighth Air Force, a complementary command to that of the smaller Ninth Air Force, Twelfth Air Force, and Fifteenth Air Forces. As the oldest command, which had begun the earliest American operations in Europe as VIII Bomber Command, the Eighth had provided British liaison and strategic tasking guidance to each of those younger organizations throughout the war." May I join the Military and War Group - is it necessary? G
