This manual, Army Techniques Publication ATP 3-39.20 Police Intelligence Operations May 2019, provides guidance for commanders and staffs on police intelligence operations (PIO). PIO is an integrated military police task that supports the operations process and protection supporting tasks across all phases of conflict by collecting and providing police information and police intelligence products to enhance situational understanding, protect the force, and assist homeland security across the operational environment. Military police and United States Army Criminal Investigation Command (USACIDC) personnel collect information as they conduct military police operations throughout the operational area. PIO supports decisive-action tasks (offensive, defensive, and stability or defense support of civil authorities [DSCA]) by planning and directing the collection, production, and dissemination of police information and police intelligence products that identify and analyze crime problems, environmental factors creating crime opportunities, and criminal actors that may affect the operational environment.

This publication is written for military police and USACIDC Soldiers and Civilians conducting PIO. This publication focuses on establishing the framework of PIO, guiding the conduct of PIO, and describing the integration of police intelligence products within the three military police disciplines (police operations, detention operations, and security and mobility support) in support of Army operations through the integrating processes.

The principal audience for ATP 3-39.20 is Army leaders and Army professionals at all echelons tasked with planning, directing, and executing PIO. Trainers and educators throughout the Army will also use this publication.
