This UFC provides technical information and guidance on physical security measures for HRP. The document focuses on two building types: (a) the HRP office and (b) the HRP residence. Determining the level of protection and associated protection measures for a HRP is the responsibility of the Protection-Providing Organization (PPO). The PPO refers to the U.S. Army Criminal Investigative Command, the Naval Criminal Investigative Service, the U.S. Air Force Office of Special Investigations, the Defense Criminal Investigative Service, the Pentagon Force Protection Agency, and the National Security Agency. As required by Department of Defense Instructions 2000-16 DoD Antiterrorism (AT) Standards and O-2000.22 Designation and Physical Protection of DoD High-risk Personnel (HRP), the PPO will conduct a Personal Security Vulnerability Assessment (PSVA) for each HRP. The resulting PSVA will provide recommendations for the protection of the HRP.
