It depends on the Army branch the Cadet chooses and the unit to which he/she is assigned. However, Army missions and challenges are always changing, so there’s no way to know in advance which specialties and units will be needed where. All Soldiers in the Army or Army Reserve face the possibility of deployment at some point during their careers. But all Soldiers are fully trained and proficient in the tasks and drills of their units. And Officers are specifically trained to make the right decisions so that missions can be carried out safely and successfully.
