The Navy Reserve is a branch of the United States Navy that allows individuals to serve part-time while maintaining civilian careers or education. Reservists typically train one weekend a month and participate in annual training, ensuring they are ready to support the Navy during emergencies or conflicts. Members of the Navy Reserve can be called to active duty when needed, providing essential support in various roles, including logistics, medical, and engineering. This structure enables the Navy to maintain a larger force without the need for a full-time military commitment from all personnel.
