If what DSAT Man said is correct
Alexrey, like you, I haven't a clue who DSAT Man is? This is a rumour network, you simply cannot base life decisions on what you read on such a site - when you are ready to do so, write to the RAF/RN/AAC (as appropriate) with all the relevant information that they may need to consider your enquiry/application - then, again, base any decision on the responses you receive from each Service.
I wish you well.
