The Army Medical Department has four major functions. Three are prevention, treatment, and evacuation. What is the fourth?

The correct answer is C, 'Mobilization.' In the context of the Army Medical Department, mobilization refers to the process of preparing and organizing medical personnel and resources for deployment during military operations. While preparation, training, and selection are important functions within the military medical field, mobilization specifically relates to the readiness and deployment of medical assets in response to operational requirements, making it the fourth major function of the Army Medical Department.
