Army Tactics, Techniques, and Procedures (ATTP) 3-39.32 provides doctrinal guidance for personnel who are responsible for planning and executing physical security programs. It is the basic reference for training security personnel and is intended to be used in conjunction with the Army Regulation (AR) 190 series (Military Police), Security Engineering Unified Facilities Criteria (UFC) publications, Department of Defense (DOD) directives, and other Department of the Army (DA) publications. This publication applies to the Active Army, the Army National Guard (ARNG)/Army National Guard of the United States (ARNGUS), and the United States Army Reserves (USAR) unless otherwise stated. Prevention and protection are the two primary concerns of physical security; both serve the security interests of people, equipment, and property. This ATTP establishes physical security as a supporting component of the protection warfighting function and describes defensive measures that enable protection tasks, such as operations security, antiterrorism, operational area security, survivability, and information protection.
