Reservists are individuals who serve in the military part-time while maintaining civilian jobs or education. They typically undergo training and can be called upon to support active-duty forces during emergencies, conflicts, or natural disasters. This allows them to contribute to national defense without being in the military full-time. These dedicated men and women often belong to branches like the Army Reserve, Navy Reserve, or Air Force Reserve. Their unique role helps ensure that the military has enough personnel to respond quickly to various situations, while also allowing them to pursue their personal and professional lives outside of military service.
