US senators question plan to disband 3rd drone battalion

A bipartisan group of US senators is questioning the US Army’s plan to disband the 3rd battalion of the 504th Parachute Infantry Regiment, a unit created to study changing battlefield technology in Ukraine.

Former US Army chief of staff Gen. Randy George founded the battalion in November 2025. Acting chief of staff Gen. Christopher LaNeve later announced plans to disband it as part of a “back to basics” approach, less than a year after its creation.

In a letter, senators Jeanne Shaheen, Thom Tillis and Angus S. King, Jr., along with Rep. Michael R. Turner, asked Army Secretary Daniel Driscoll and Gen. LaNeve to provide the data and analysis behind the decision. They also questioned whether it followed Department of Defense guidance or was an internal Army decision.

The lawmakers said eliminating the specialized unit could limit the US military’s ability to learn from the Ukrainian Armed Forces and modernize drone warfare. They requested a briefing on how the Army will continue learning from Ukraine without the Unmanned Assault Battalion, no later than September 21st, 2026.

The letter points to battlefield developments including autonomous drones used against Russian Shahed drones and ground robots carrying 210 kilograms across open ground. Without a dedicated unit to deploy or test systems, the Army may miss lessons that could shape future conflicts.
