The Military Health System (MHS) is one of America’s largest and most complex health care institutions, and the world’s preeminent military health care delivery operation. The central MHS mission is support of health readiness – the readiness of individual service members and the readiness of the medical team in support of the Combatant Commands and Military Departments. The Defense Health Agency (DHA), Office of the Joint Staff Surgeon (JSS), and Military Department medical organizations are responsible for ensuring the operation of an integrated system of readiness and health to improve and sustain operational medical force readiness. Collaborative efforts across the MHS aim to optimize force health protection and medical readiness based on meticulous research, lessons learned, and best practices. These efforts enable medical providers in theater and in military hospitals and clinics to improve, protect, and sustain Servicemember health readiness and resilience. The MHS plenary session includes a senior leader panel moderated by the Deputy Assistant Secretary of Defense for Health Readiness Policy and Oversight, Dr. David Smith, and featuring the Defense Health Agency (DHA) Director, the Uniformed Services University (USU) President, the Joint Staff Surgeon (JSS), and the service Surgeons Generals.
