No-one has actually answered the question!
Been thinking outside of the box lately and wondering whether or not the AAC or indeed either of the other services would be interested in me; bearing in mind I'm now thirty.
The upper age limit for AAC commissioned service is I think 28 on entering RMAS. Waivers may be possible, but an RMAS place is no guarantee of an offer from AAC.
