If you're looking to challenge yourself mentally and physically then a career as a General Service Officer could be for you. A GSO is someone who is committed, shows initiative, works well in a team environment and has leadership potential. You may have already studied at university or have worked for a couple of years since leaving school. Your training will teach you how to think, not what to think. At the end of your training, you will have the ability to lead and the ability to make decisions confidently.
