I am currently a MAN in Signals. Will I not be able to sign on as a sergeant after I ORD? How does sign on works for MAN in the army?
your query would be normal if you are a pre-enlistee. But given that you are already in active service, it is surprising that this is still your question.
what i can tell you is that to be in the specialist rank would not be possible even after sign-on.
as for your 2nd question on how does the man (CFC and below) works in the army, my guess is that you are now already having the ground experience.
my advice to u is that, if you are interested in doing what you are doing now after ORD, u can consider civilian positions offered by companies out-sourced by Mindef.
