I've recently applied to join the British army, I've filled out my application and have an appointment to speak to a careers advisor. I've just signed the forms to allow them to obtain my medical records. I'm 33 reasonably fit. 6'5, so my BMI is slightly higher. I'm looking for advice as to how to prepare myself for the training and assessments. What should I be focusing on and have you any valuable advice to offer me as I embark on this next chapter of hopefully joining the Army. I'm undecided on which role within the army I will go for. So all advice and insights are welcome.
