The Military Health System (MHS) is a comprehensive network that provides healthcare services to active-duty service members, veterans, and their families. It includes hospitals, clinics, and various medical facilities operated by the Department of Defense (DoD). The MHS aims to ensure that military personnel receive high-quality medical care, both in peacetime and during deployments. In addition to direct medical services, the MHS focuses on health promotion, disease prevention, and rehabilitation. It also conducts research and development to improve medical practices and technologies. The system plays a crucial role in maintaining the overall health and readiness of the U.S. Armed Forces.
