If in wrong forum - please advise! Many Views no Replies! Though many forums reference my query, I have started this new subject for two reasons: (i) The information in these forums does not cover the specific problem (outlined herein) and (ii) It may become an interesting topic of further discussion. Question: Should a Service No not change if comissioned from ranks! If someone I'm background checking went from IJLB to the Coldstream Guards, I assume correctly his Service Number would transfer? His stated number is within correct range for year of enlistment to IJLB! But after only 14 months he is transfered due injury and personal request to RAMC. Again assume his no transferred, but he is later commisioned (SSC) as a Medical Logistics Officer (no medical trade)! Now if my own service experience is correct, would he not be reissued an Officers Service Number? For example, QARANC if memory serves me correcly is 5 or 6 digit. He appears to retain the same number throughout later service - including discharge on medical grounds (QR is correct) and transfer to Regular Reserve for another 12 years service with RAMC(V). Including two FTRS in Kosovo and Afghanistan 1999, 200, pre JPA. so again his service number (8 digit) retained. On completing a TACC he is promoted (2 Lt to Lt) and again original 8-digit service no. I think everything else is Kosher - just his rank - which dosen't fit timelines on his Red Book papers. Gazette shows a person of his name and rank - but with an officers number (not 8 digit)! So if commisioned from the ranks would his service no change accordingly? And maybe have Glasgow and APC f'kd up and not noted both numbers on his discharge doc's. Any ideas or comments received most welcomed!
