"
The C15TA was used by (...) some British Units in the Far East, such as the 5th Parachute Brigade. Within the British Airborne Forces some were converted to provide a ‘Command Vehicle’ at Battalion and Brigade level, and were fitted with extra radios’."
This photo was reportedly was made on 23 July 1945. To me it seems that if the C15TA was indeed used by British Airborne Forces, it was in the early postwar years?
Who knows the details?
