This United States Army Military Police manual, Army Techniques Publication ATP 3-39.30 Security and Mobility Support May 2020, examines the military police discipline of security and mobility support and how military police support Army, joint, and multinational forces by conducting the tactical tasks and activities associated with security and mobility support. ATP 3-39.30 provides military police commanders, staffs, and Soldiers a foundation for the conduct of security and mobility support across the range of military operations. The focus is primarily on those tactical tasks and activities (facilitated by military police technical capabilities) that enable the elements of combat power. It describes how military police are employed to protect the force and noncombatants and how they facilitate the preservation of the commander’s freedom of action. The security and mobility support discipline enables and is enabled by the other military police disciplines of police operations and detention operations. Each discipline is seen through a policing or corrections lens and is driven by the integrating function of police intelligence. Police intelligence operations (PIO) support commanders at all levels through the integration of police intelligence activities within all military police operations. The disciplines are interdependent areas of expertise within the Military Police Corps Regiment. The tasks in this discipline are focused on those military police tasks that are typically performed in a tactical environment, and while military police are the proponent for many of these tasks, some of these tasks may also be performed by other members of the combined arms team. Military police conducting tasks within the security and mobility support discipline are typically in a support role. These tasks are primarily focused on applying military police combat power in support of the movement and maneuver and protection warfighting functions; however, security and mobility tasks also support the conduct of populace and resources control (PRC). Military police perform many security and mobility support tasks and activities in the support area, making them a significant enabler to the sustainment warfighting function. Security and mobility support is enabled and facilitated by the technical tasks embodied in the military police disciplines of police operations and detention operations. These disciplines and the integrating function of PIO are described in-depth in other military police manuals and will be referred to when they are critical to discussions supporting the discipline of security and mobility support. ATP 3-39.30 includes significant changes from previous versions. It is divided into five chapters and four appendixes.
