Hi Tulablu, your posts on this thread are somewhat confusing, starting with the thread title itself. You need to wind things back a bit if you want advice, and state what RAF role or roles you’re interested in. That will determine what qualifications you need in order to apply. All of this is available on the RAF careers website or by talking to a recruiter in your nearest Armed Forces careers office.
And just for clarity, RAF camps are rarely known as Barracks, except by the media and uninformed commentators. Barracks are where Army troops live and work. I suspect you may be placing too much reliance on AI to produce your posts, rather than using your own words.
