Joint Interagency Task Force 401 (JIATF 401) has released a new guide aimed at helping military installation commanders and local law enforcement better protect critical infrastructure from threats posed by small UAS.
Titled the JIATF 401 Guide for Physical Protection of Critical Infrastructure, the document provides an accessible framework for assessing risk, identifying vulnerabilities and implementing practical, passive protective measures against hostile or malicious drone activity. It draws heavily on lessons learned from recent conflicts and real-world operational experience.
The guide is intended to support a wide range of users, including base defenders, security forces, interagency partners and law enforcement personnel responsible for safeguarding assets vital to national security.
At the core of the guidance is the “Harden, Obscure, Perimeter” framework, which focuses on shaping the physical environment to counter drone threats without relying on high-end or complex technology. Hardening measures include physical obstacles such as netting or structural shielding to impede drone flight. Obscuring techniques aim to limit a drone’s ability to identify and access sensitive assets through visual clutter or temporary barriers. The perimeter element extends defensive measures beyond traditional fencelines, creating layered protection designed to detect and deter threats before they reach their target.
“The release of this guide demonstrates our whole-of-government effort to defend the Homeland,” said Army Brig. Gen. Ross, Director of JIATF 401. He noted that homeland defence extends beyond military bases to include public spaces where Americans gather, adding that with major international events such as the World Cup approaching, the protection of venues like stadiums has become a national priority.
Ross emphasised that the principles outlined in the guide apply across a wide range of settings, from forward operating bases to concert venues and major sporting events:
“Countering the drone threat is about more than exquisite systems,” he said. “This guide highlights the steps we can take now to prepare and protect critical infrastructure.”
The publication is the result of collaboration across multiple U.S. government organisations, including experts from the Office of the Secretary of War for Policy, Acquisitions and Sustainment, and Research and Engineering, as well as input from fielded forces. It was released in support of the White House FIFA Task Force.
By establishing a common lexicon and set of best practices, JIATF 401 said the guide is intended to improve coordination and interoperability across federal, state and local agencies involved in infrastructure defence operations nationwide.
