What must a UDM do after receiving a tasking to ensure medical clearance for personnel?

When a UDM receives a tasking to ensure medical clearance for personnel, the most appropriate action is to alert the base medical facility about the deploying personnel. This is crucial because the medical facility must be informed in order to prepare for the upcoming medical examinations and assessments required for clearance. By notifying the medical facility, the UDM ensures that there is awareness of the personnel needing clearance, which facilitates the scheduling of their examinations and helps keep the deployment timeline on track.

Taking this step is essential as it helps in managing the health and readiness of the deploying individuals, ensuring that they meet necessary medical standards before deployment. The base medical facility can then address any potential medical issues, provide necessary vaccinations, and ensure appropriate documentation is completed, all of which are key to a successful deployment process. While other actions like scheduling medical examinations and preparing files are important, they are secondary to the immediate requirement of notifying the medical facility.
