The Navy Reserves is a part-time branch of the United States Navy that allows individuals to serve on a part-time basis while maintaining a civilian career. Reservists train one weekend a month and two weeks a year, and can be called to active duty in times of need. They play a vital role in providing support to the active duty Navy in areas such as combat operations, humanitarian assistance, and disaster relief. The Navy Reserves provide a valuable supplement to the Navy's overall capabilities and readiness.
