I am a student in Y9 and my school is offering the Combined cadet forces to our year. I am a little interested in it but I do not know for sure what actually happens. Do you guys recommend that I sign up for it and what are its perks. Please also take into consideration that I am a larger teenager and not as fit as others my age.I have heard from many that programmes like cadets are full of intense training which require a lot of fitness-is this true?
