Joint Interagency Task Force 401 (JIATF 401) announced the publication of the "JIATF 401 Guide for Physical Protection of Critical Infrastructure," a critical document designed to help installation commanders and local law enforcement use passive measures to secure some of the nation's most vital assets against threats from small unmanned aircraft systems (sUAS), or drones.
Taking key lessons learned from the battlefield, JIATF 401 developed the guide to provide an accessible framework for assessing risks, identifying vulnerabilities, and implementing effective protective measures. It will serve as a resource for commanders, base defenders, interagency partners, law enforcement, and security forces responsible for safeguarding infrastructure critical to national security.
A central concept of the guide is the "Harden, Obscure, Perimeter" framework, a methodology focused on shaping the physical environment to counter sUAS threats. This approach emphasizes practical, layered solutions that can be implemented without the need to procure and deploy exquisite technology. Hardening involves creating physical obstacles to sUAS flight, such as netting or structural shielding. Obscuring focuses on reducing a drone's ability to identify and access critical assets through measures like visual clutter and temporary barriers. The perimeter aspect extends security well beyond the traditional fenceline, creating layered defenses to detect and deter threats before they reach the intended objective.
"The release of this guide demonstrates our whole-of-government effort to defend the Homeland," said Army Brig. Gen. Ross, Director of JIATF 401. "When we talk about Homeland defense, we're not just talking about military bases, power grids and ports; we're talking about places where Americans gather. With major international events like the World Cup on the horizon, the security of our stadiums, for example, is a national priority."
Brig. Gen. Ross continued, "Whether it's a forward operating base, an outdoor concert venue or a stadium hosting the World Cup, the principles of risk assessment and physical protection outlined in this guide remain the same. This new guidance provides a common playbook for our forces to work closely with federal and local partners to ensure a safe and secure environment against the growing challenge of nefarious drones. Countering the drone threat is about more than exquisite systems. This guide highlights the steps we can take now to prepare and protect critical infrastructure."
This guide represents the work of numerous partners including experts in the Office of Secretary of War (OSW) for Policy, OSW Acquisitions and Sustainment, and OSW Research and Engineering, along with input from fielded forces. It was published today in support of the White House FIFA Task Force.
The guide establishes a common lexicon and best practices that will improve coordination and interoperability for infrastructure defense operations nationwide.
