# Army Cyber Command Seeks Agentic Cyber Capability

The U.S. Army Cyber Command’s ECHOTRIBBLE notice seeks an agentic command-and-control capability that can autonomously navigate computer networks and disable or remove targets with minimal human oversight, including stealth, self-directed execution, and rule-bound propagation. Whitepapers were due August 13, 2026, demonstrations occurred October 6–8, and selections were expected around October 15; as of October 21, the Army had not confirmed selections. The notice describes potential prototype awards and production contracts without competition if prototypes succeed, but the signals provide no contract value or confirmed award.

- The opportunity’s prototype phase and possible follow-on production make prototype performance and the stated capability requirements central considerations for interested contractors.
- The notice describes deployment in contested, air-gapped, or cloud-native systems. Contractors evaluating the opportunity should account for those operating environments and the requested autonomy features.
- The signals identify risks of unintended effects on third-party systems and uncertainty about safeguards. These are material operational considerations for government buyers and companies developing or supporting the capability.
- The expected selection timeframe has passed without confirmation in the supplied reporting; the signals do not establish an award or provide a confirmed next-step schedule.
