A Field Surgeon can either enter Medical School as an officer on the HPSP scholarship or go to a service academy. If you go to a service academy you have to give back 5 years or service, 2 have to be active duty. Or you can go the ROTC route for undergraduate college to pay for the civilian college while participating in the ROTC program (pay back 4 years). But, if a students goes the HPSP scholarship route, then you undergo military training and medical school at the same time. You give back however many years you are in school to active duty service. If a cadet from an academy goes to medical school they also follow the same time serving however many years in graduate schooling as the years you give back.
