About Military Health System
The Military Health System is the enterprise within the United States Department of Defense that provides health care to active duty and retired U.S. Military personnel and their dependents. Its mission is to provide health support for the full range of military operations and sustain the health of all who are entrusted to MHS care.
Its primary mission is to maintain the health of military personnel, so they can carry out their military missions; and to deliver health care during wartime. Often described as the medical readiness mission, this effort involves medical testing and screening of recruits, emergency medical treatment of troops involved in hostilities, and the maintenance of physical standards of those in the armed services.
