Hi Emily, There isn't a 'field medic' role as such, but there are clinicians who work in the field. It depends on what type of clinician you want to be as to whether you go through sandhurst to commission as an officer, or whether you train as a soldier. The website has a list of the roles available, and each page will explain what the entry requirements are, as well what initial training involves. https://apply.army.mod.uk/roles if you click the 'medical' option on the left hand side under job type this will help.
