If you join straight away then you will have to put up with booty-issue ballgowns and lingerie. If you transfer in and do the all-arms course then you will have had the opportunity to sort out your own girlie kit for yourself.
Apparently RM-issue stuff is all Ann Summers cast-offs, chafes on the old you-know-whats. OTOH, the SBS wear Janet Reger. Who have their own concession in the NAAFI at Poole.
Listen kiddo. If you post immature innane cr@p in the NAAFI Bar (read what it says at the top) then expect to get riddiculed. Have you not read through any of the other threads. In Army speak that would constitute a recce, the idea being - is it safe! If you can't hack it here, how the hell do you expect to survive in the Army?
Have a look at the threads on this site. I think you'll find that it's called banter. When you've gone through puberty and if you do join you will come across it everywhere you go. There's a saying - "if you can't take a joke then you shouldn't have joined!" or in your case "if you can't take a joke, don't bother joining."
Plus check the warning out on the link for the NAAFI BAR "Look some of the stuff in here is really quite nasty. If you are easily offended - DO NOT ENTER."
Lesson in life - if something has a warning like that don't post here!
EDITED - SORRY LEGS I WROTE THIS AT THE SAME TIME YOU POSTED YOURS.
