The Pentagon has released new guidance outlining how military commanders and local law enforcement can protect critical infrastructure and public gathering spaces from threats posed by small drones, relying on physical and passive security measures rather than advanced counter-drone technology.
The guidance was published Jan. 30 by Joint Interagency Task Force 401, a Department of Defense unit focused on countering unmanned aerial system (UAS) threats. Officials said the document is intended to help safeguard military installations, critical infrastructure, and civilian venues such as stadiums and outdoor event spaces.
The release comes as federal agencies intensify preparations for large-scale public events in the United States, including the 2026 FIFA World Cup, as The Dallas Express previously reported.
A Shift In How Facilities Are Defended
Rather than emphasizing high-tech counter-UAS systems, the new guide promotes a framework known as “Harden, Obscure, Perimeter,” which focuses on shaping the physical environment to reduce drone risk.
According to the task force, the approach is designed to be implemented immediately, often at modest cost, using existing materials and personnel.
- Hardening involves introducing physical obstacles that disrupt predictable drone flight paths, such as netting, structural shielding, or overhead barriers
- Obscuring reduces what a drone can identify or exploit by limiting clear lines of sight through visual clutter, temporary walls, or protective coverings
- Perimeter thinking extends security planning well beyond traditional fence lines, creating layered defenses in surrounding areas where drone operators are more likely to be positioned
The guide emphasizes that many of these measures can deter or complicate the use of low-cost, consumer-grade drones without requiring specialized equipment.
Focus On Public Venues And Critical Infrastructure
“This guide demonstrates our whole-of-government effort to defend the homeland,” said Army Brig. Gen. Matt Ross, Director of Joint Interagency Task Force 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,” Ross said.
He cited upcoming international events as examples of venues where the guidance can be applied.
“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,” Ross said.
Practical Steps Over Advanced Systems
The document stresses that countering drone threats does not require waiting for advanced or “exquisite” technology to be fielded.
“Countering the drone threat is about more than exquisite systems,” Ross said. “This guide highlights the steps we can take now to prepare and protect critical infrastructure.”
The guide was developed with input from multiple Pentagon offices, including policy, acquisition, sustainment, and research divisions, as well as operational forces in the field. It was published in support of the White House’s FIFA Task Force, which is coordinating federal security planning for the tournament.
Officials said the document establishes a shared set of terms and best practices intended to improve coordination between federal, state, and local authorities as drone threats to public spaces continue to grow.
