7-98. AHS is the Army component of the military health system. Its capabilities are focused on delivering health care across the continuum of military operations from the point of injury or wounding, through the joint operations area, to the CONUS support base. The two missions of the AHS are to provide health HSS (casualty care, medical evacuation, medical logistics) and FHP (casualty prevention). The AHS is focused on promoting wellness, preventing casualties due to disease and nonbattle injuries, and providing timely and casualty care and management. Medical evacuation is the vital factor in ensuring the continuity of care provided to our Soldiers by providing en route medical care during evacuation, facilitating the transfer of patients between medical treatment facility to receive the appropriate specialty care, and ensuring scarce medical resources (personnel, equipment, and supplies [to include blood]) can be rapidly transported to areas of critical need on the battlefield.
7-99. The provision of AHS is governed by well-established and time-tested principles and rules which ensure the care provided to our Soldiers is timely and effective. (Refer to FM 2-02 for more information.)

7-1011. The AHS has two main missions: to provide HSS and to provide FHP. The HSS mission is comprised of casualty care (area and organic medical treatment, hospitalization, the treatment aspects of combat and operational stress control and dental services, and clinical laboratory services), medical logistics, and medical evacuations. It is aligned under the Sustainment Warfighting Function. The FHP mission is aligned under the Protection Warfighting Function and is comprised of preventive medicine, veterinary services, the preventive aspects of combat and operational stress control and dental services, and area medical laboratory.
7-102. AHS resources are arrayed across the battlefield in successive levels of support. These successive levels have increased medical care capabilities at each higher level. Medical evacuations and provision of en route medical care ensures an uninterrupted continuum of care is maintained while Soldiers are moved through the roles of medical care to the medical treatment facility best suited to treat the patient’s specific injuries.
