A Joint Reserve Base (JRB) is a military installation that supports both active duty and reserve components of the armed forces. These bases are designed to enhance operational efficiency by allowing different branches, such as the Army, Navy, Air Force, and Marine Corps, to share resources and facilities. This collaboration helps streamline training and logistics while reducing costs. JRBs often host various units, including reserve squadrons and support organizations. They provide essential services like maintenance, medical care, and administrative support. By fostering cooperation among the military branches, JRBs play a crucial role in national defense and readiness.
