I am trying to find records for my dad. My dad was in Royal Marines during the 2nd world war and I have Nos and unit for that so presumabbly get hold of those records. After the War he was in REME ( Royal electrical and mechanical engineers ) and worked for one or other dept of MOD til he retired. I have been in contact with the Army records office by phone and they can find no trace of him with his date of birth. The online request forms state that the service Nos and units are required but I have no idea of these . Can anyone point me in the right direction?
