About the Military Health System

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. Our MHS saves lives on the battlefield, combats infectious disease around the world, and cares for 9.4 million beneficiaries in one of the nation’s largest health benefit plans.

The missions of the MHS are complex and interrelated:

  • To ensure America’s 1.4 million active duty and 331,000 reserve-component personnel are healthy so they can complete their national security missions.
  • To ensure that all active and reserve medical personnel in uniform are trained and ready to provide medical care in support of operational forces around the world.
  • To provide a medical benefit commensurate with the service and sacrifice of more than 9.4 million active duty personnel, military retirees and their families.
