The U.S. Navy Reserve is a branch of the United States Navy that allows individuals to serve part-time while maintaining civilian careers or education. Members, known as reservists, typically train one weekend a month and participate in annual training, ensuring they are ready to support the Navy during times of need. Reservists can be called to active duty during emergencies, conflicts, or national crises. They play a crucial role in supporting naval operations, providing specialized skills, and enhancing the overall readiness of the U.S. Navy. This structure allows the Navy to maintain a larger force without the need for a full-time military commitment from all personnel.
