A Joint Reserve Base (JRB) is a military installation that supports both active duty and reserve components of the United States Armed Forces. These bases allow for efficient use of resources and facilities by combining the efforts of different branches, such as the Army, Navy, Air Force, and Marine Corps. JRBs provide essential training, administrative support, and logistical services to reserve units. They help maintain readiness and ensure that reservists can seamlessly integrate with active-duty forces when needed. This collaboration enhances operational efficiency and strengthens national defense capabilities.
