The New U.S. Army Pocket Guide

A new handbook gives troops pointers on how to scan the sky for drones, how to estimate the length of a football field, and reminders that innocuous things like the shine of their glasses or left-behind MRE garbage can give their position away.

Published Tuesday by the Pentagon’s Joint Interagency Task Force – 401, the 2026 Counter-Small Unmanned Aircraft Systems Quick Reference Guide includes drone tactics, techniques and procedures and a catalogue of drones and counter-UAS technologies currently in the U.S. inventory, including lasers, jammers, and interceptors. Task Force – 401 was set up in 2025 to coordinate drone defense and tactics across the services. 

HERE is the C-UAS Quick Reference Guide, available for free download.
