Military Police (MP) authority and limits on base can be summarized as follows:
-
Jurisdiction: MPs have authority primarily over military personnel, military areas, installations, and exercise areas. Their jurisdiction is generally confined to military bases and property under military control.
-
On Base Responsibilities: MPs enforce military law, including the Uniform Code of Military Justice (UCMJ), and military orders and regulations on base. Their duties include criminal investigations, traffic enforcement, emergency response, base access control, corrections, and maintaining law and order within the military community.
-
Authority Over Civilians: MPs typically do not have jurisdiction over civilians off base. Civilians on base may be detained by MPs for a reasonable period until handed over to appropriate civilian authorities. Exceptions to this are rare and usually involve specific legal authorization, such as national security concerns.
-
Limits: The Posse Comitatus Act generally prohibits military personnel, including MPs, from enforcing civilian laws off base, except under very limited and specific circumstances. This ensures the military is not used as a police force over the civilian population.
-
Chain of Command: Military Police Officers (commissioned officers) have broader authority and responsibility than enlisted MPs. Officers oversee law enforcement administration on bases and command enlisted MPs.
-
Additional Roles: MPs also protect key military personnel and installations, secure vital military infrastructure, and may serve as bodyguards for high-ranking officials.
In summary, Military Police have broad law enforcement authority within military installations but their power over civilians and off-base activities is limited and regulated by law and military policy. Their primary role is to maintain discipline, law, and order among military personnel and protect military assets on base.
