- Four Ps: person, platform, process, payload
- Five Ds: detect, deny, disrupt, defeat, discipline
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 AssessmentWhat Changed
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.
Who is Affected
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.
Why it Matters
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.
Before Next Mission
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.
What Not to Assume
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.
