How Do I Report a Crime on the Installation?

If you are the victim of a crime on an installation, or the victim of a crime off of an installation that involved military personnel, you can report the crime to the nearest military police agency. You can also call "911" at any time if you have an emergency or need to report an incident.

Military law enforcement overview

Military police protect lives and property on Department of Defense (DoD) installations by enforcing military laws and regulations, as well as controlling traffic, preventing crime and responding to emergencies. Each of the branches of Service has its own military police force, with the exception of the Coast Guard, which is in itself a law enforcement agency within the Department of Homeland Security (DHS). Although the branches of Service do not use the same terminology when referencing their military police forces, their responsibilities are the same. In the Army and Marine Corps, installation law enforcement activities are led by the Provost Marshall, while in the Navy these activities are led by the Chief Master-at-Arms (CMAA). In the Air Force, these activities are led by the Air Force Security Forces (SF).
