As a recruiter, I'd have to say finish school. You only require to have 15 credits (Prov of Ont), however if you're looking to go Reg force, CFRC is looking for grade 12. Even the infantry is a competitive trade (not intended as a slight to the "Queens of the battlefield"). The more education you have, the more competitive you'll be. As a turned around "Young, know everything punk" I would also have to say. With out a highschool education, you'll get no where on civie street either. My advice. complete the 15 credits, join a reserve unit, get some crses and experience, finish highschool (maybe even college) and then go reg if that's your plan. Always have a back up plan. The military is not a job for everyone. Saying that though, if you do feel it's for you, it can be the most rewarding job/career any one can ever have.
