well. think about what you might need to start off with. ( make sure you don't bring anything your not allowed to bring, your CO should of told all the cadets what that is)
they supply all the kit at the camp. so all you need to bring is all your hygiene stuff, some civilians ( in case you are allowed to wear them, i am not sure of the rules now). you would pretty much bring what ever you would take on a cadet activity, but enough for 2 - 6 weeks depending on the course.
EDIT: just relized there is another thread with all the info suplied by burrows
