I am researching family history for my wife. her father was in the RAF Servicing Commando's, but I am unable to trace which Unit he was attached to. I think it may have been 3210 as he landed on Overlord on D-Day plus 1..He was Cpl. William Charles Risley 1453444.His Service and release book shows overseas service, France Jun44 to May 45 and Iraq Dec 45.I would like to confirm the unit to continue my research.
