Which document governs the deployment and use of medical resources in military operations?

The correct choice is Joint Publication 4-02, which serves as a comprehensive framework for the deployment and utilization of medical resources during military operations. This document provides vital guidance on all aspects of military medicine, including the operational capabilities, healthcare resources, and the organization required to support medical functions in joint operability.

Joint Publication 4-02 emphasizes the principles of medical support to operations from the strategic level down to tactical execution. It integrates various facets of military healthcare, ensuring that medical resources are effectively coordinated and utilized across different branches of the military during joint operations, which is essential for mission success.

While other documents, such as NAVMED P-5132, the Operational Medicine Policy, and NAVMEDCOMINST 6000.1, play important roles in specific areas of military medicine and policy, they do not serve the broad operational purpose that Joint Publication 4-02 fulfills. They may govern certain medical practices or policies, but they do not encompass the overall guidance for deploying and managing medical resources in operations as explicitly as Joint Publication 4-02 does.
