Police operations have historically been understood to consist of LE missions supporting U.S. military commanders and their efforts to police our military personnel, civilians, and family members working and residing on U.S. military bases and base camps. Bases and base camps refer to any U.S. military installation, base, or other location within the United States and enduring installations, bases, or other locations outside the United States employed to support long-term military commitments and/or serve as power projection platforms. U.S. Army doctrine has not historically focused on police operations outside of LE support to bases and base camps. Police operations support to the operational commander and the capabilities inherent within LE organizations have been growing in relevance to the Army over the past decade. Recent conflicts and the nature of the threat within the operational environment have increased the relevance of police operations and LE capabilities in support of Army operations. The applications of police operations and the requirements for Army LE personnel to conduct these operations have grown tremendously as nation building and protracted stability operations have demonstrated the need for civil security and civil control as critical lines of effort within the larger effort to transfer authority to a secure and stable HN government. Lessons learned from recent conflicts, coupled with task analysis conducted by USAMPS, Fort Leonard Wood, Missouri, have resulted in an expanded doctrinal framework and understanding of police operations. The expanded framework does not establish new tasks within the police operations discipline, but identifies and documents missions and tasks in the revised doctrine that have historically been conducted by military police. Recent updates to military police doctrine establish police operations as the primary military police discipline, shaping the actions and perspectives of military police in the conduct of military police disciplines. These updates describe police operations within the context of two activities-policing and LE. Policing activities are general actions aimed at establishing order and stability within an area of operations (AO); LE activities are tied to the rule of law and require specific training and authority for the element or personnel performing the actions. While military police are uniquely qualified to conduct policing, these activities do not require personnel specifically trained for LE activities. LE activities require specific training and may only be conducted by LE personnel (military police, USACIDC special agents [SAs], or other trained and certified LE personnel).
