In cooperation with the Joint Staff Surgeon and Military Department medical organizations, DHA leads the Department of Defense integrated system of readiness and health through a global healthcare network of military and civilian medical professionals, including military hospitals and clinics around the world, to improve and sustain operational medical force readiness and the medical readiness of the Armed Forces.
Enhancing Military Readiness through Combat Support Capabilities
The DHA provides support for operating forces engaged in planning for, or conducting, military operations, including support during conflict or in the conduct of other military activities related to countering threats to U.S. national security. Among DHA’s most important combat support responsibilities is its work to increase readiness of U.S. forces to carry out their deployed missions.
The DHA fulfills its combat support responsibilities through capabilities including several components that provide crucial expertise and support to the Combatant Commands.
