I was posted, as an instructor (telegraphist), to 3 Maritime HQ, RAuxAF in 1970 after spending 3 years attached to 24 (Airportable) Infantry Brigade. My boss refused to believe that the RAuxAF was still in existence but upon enquiring discovered that 1, 2 and 3 MHU were still going strong. I retired from 3 MHU in 1973.
