Recently left the RAAF after 32 years service.
Got an e-mail a few weeks before, asking me to confirm my service record (units etc) was correct for my Certificate of Service.
2 Days prior to departing was presented with same. Large certificate with Rank, name, number etc and a list of all the units I had ever served in, and personally signed by CAF (whom I know personally). Its quiet a good looking certificate.
Only issue was that it arrived unframed. The RAN Commodore I worked for in my last job thought this was quiet wrong, so ensured that said certificate was professionally framed (and paid for from his corporate funding I understand) and as he was away that day, arranged for a suitable senior officer from the RAAF to present it to me. Unfortunately Binny (another personal friend) was away that day as well.
It does look good on my "I love me" wall.
