Pentagon’s New Joint Counter-UAS Handbook: What It Actually Says

Joint Interagency Task Force 401 published a 90-page orientation handbook establishing the Four Ps and Five Ds. It is a shared vocabulary, not domestic scanning or an FAA rule.

Pentagon’s New Joint Counter-UAS Handbook: What It Actually Says
Correction: An earlier version of this page listed the handbook’s “Four Ps” as Payload, Proximity, Persistence, and Portability, and the “Five Ds” as Detect, Decide, Disrupt, Defeat, and Document. The handbook itself uses:
  • Four Ps: person, platform, process, payload
  • Five Ds: detect, deny, disrupt, defeat, discipline
That error is material. The live copy also treated a Pentagon orientation handbook as if it were a domestic RF-scanning rollout.

The Brief

Joint Interagency Task Force 401 published Small Drones, Big Problems: A First Principles Approach to Countering-UAS, dated 18 June 2026 and released publicly in early July. It is a 90-page orientation document for warfighters, federal agencies, and local law enforcement. Brig. Gen. Matthew Ross, JIATF 401’s director, describes it as a common foundation — not a technical manual and not doctrine.

Flight-Ready Breakdown

Threat Assessment

DoD’s counter-drone task force put a shared vocabulary in one place. The Four Ps are how to assess a threat (who is flying, what airframe, how it is controlled, what it is for). The Five Ds are a sequence in which kinetic defeat is last, not first. Denial — making yourself uninteresting or hard to see — is the step the handbook says defenders skip.

Public-safety UAS programs, critical-infrastructure security, and Part 107 operators flying near sites that already attract law-enforcement attention. This is not a new FAA rule and not a new Remote ID requirement.

A first-principles handbook is not authority to jam, seize, or shoot a drone. Most of the defeat tools it describes are restricted to the military and to agencies with statutory C-UAS authority. For a private operator the useful takeaway is simpler: Remote ID on, authorization in the folder, and do not treat “I was below 400 feet” as invisibility.

If you fly near a prison, airport, stadium, or other covered site, assume detection exists. Carry the authorization you actually hold. Do not assume a handbook equals a local C-UAS program.

Do not assume this document created SLTT C-UAS authority. Congress did that separately in the SAFER SKIES Act (FY2026 NDAA, P.L. 119-60), implemented by a DOJ/DHS interim final rule effective 1 July 2026 (91 FR, 6 July 2026). That rule is a certification and technology-list framework for trained agencies — not “AeroScope and Dedrone are now scanning every metro.” Do not assume the handbook’s vignettes (Langley-Eustis 2023, Ukraine, Operation Epic Fury) are instructions for a Part 107 job.
