of the officer's normal duties, and coordinated through the Commissioned Corps's Readiness and Deployment Branch (RDB) in Commissioned Corps Headquarters (CCHQ). Deployments may be for technical needs in standard settings, or in the event of disasters, in austere environments. The commissioned corps may be militarized by an act of Congress or by executive order by the President of the United States, not only in time of war, but also in "an emergency involving the national defense proclaimed by the President." . states:In time of war, or of emergency involving the national defense proclaimed by the President, he may by Executive order declare the commissioned corps of the Service to be a military service.

Like all other federal-level responses, commissioned corps officers are deployed only upon request, and upon the recommendation of the surgeon general and permission of the assistant secretary for health. During deployments, commissioned corps officers may report to regular office spaces, such as coordinating responses at state-of-the-art emergency operations centers, or into the field in extremely austere environments, such as when responding to a natural disaster. In addition, deployments may either be on an individual basis, such as when specific skill sets are needed, or as part of a team, when large-scale responses are needed. The commissioned corps organizes PHS officers into units for rapid deployment. PHS officers are either assigned to a pre-configured rapid deployment unit (RDU) or a group augmenting those units. PHS officers must be prepared to deploy within 48 hours of receipt of
