Where is the original medical record maintained on deployed active duty and ARC personnel?

The original medical records for deployed active duty and Active Reserve Component (ARC) personnel are typically maintained at the individual service member's assigned military treatment facility (MTF) or by the designated medical records office within their respective branch of the military. In addition, during deployments, medical records may be managed and accessed through the Defense Health Agency’s electronic health record system, ensuring continuity of care. These records are crucial for tracking the health and medical history of service members while they are deployed.
