A bipartisan group of four U.S. lawmakers sent a letter to Army leadership on Tuesday, September 1, 2026, seeking an explanation for the decision to phase out a specialized drone unit based in Europe. The 173rd Airborne Brigade’s Unmanned Assault Battalion, consisting of approximately 600 soldiers, had been tasked since November 2025 with specializing in drone warfare and uncrewed systems. The lawmakers requested a briefing to understand the data and analysis that led to the unit's refocusing after less than one year of activity.
The unit was established under the Army Transformation Initiative, a program led by former Army Chief of Staff Gen. Randy George and former Army Secretary Daniel Driscoll. The initiative aimed to integrate modernized unmanned aircraft systems into standard formations and accelerate the development of new drone technologies. Defense Secretary Pete Hegseth removed Gen. George from his post in April 2026, and Secretary Driscoll submitted his resignation this week, with Wednesday, September 2, 2026, serving as his final full day in office.
Following these leadership changes, Gen. Christopher LaNeve, the Army's acting chief of staff, ordered the battalion to refocus on its core warfighting tasks as an airborne infantry unit. An Army official confirmed that the battalion will participate in exercises at the Joint Multinational Readiness Center in Germany through October before the transition. The lawmakers’ letter was addressed to Gen. LaNeve and the departing Secretary Driscoll, signed by Sens. Jeanne Shaheen (D-NH), Thom Tillis (R-NC), Angus King (I-ME), and Rep. Mike Turner (R-OH).
The change in direction follows a period of significant leadership turnover at the Department of Defense. Gen. George and Gen. Chris Donahue, both advocates for the specialized drone unit, were removed or replaced by Defense Secretary Hegseth. Critics of the phaseout, including former battle captain Cameron McMillan, stated that the Army currently faces gaps in drone defense doctrine and capacity. The lawmakers argued in their letter that specialized units are necessary when the "character of warfare is changing faster than a conventional formation’s ability to adapt."
The Army has not yet publicly responded to the request for a briefing or detailed the internal guidance behind the reversal. The battalion is scheduled to complete its current rotation at the Joint Multinational Readiness Center in Germany by the end of October 2026. Following these exercises, the soldiers will return to their primary mission as a light infantry brigade team stationed in Vicenza, Italy. It remains unclear if the Army will continue to pursue the broader drone integration goals of the previous administration or if the policy has been fully rescinded.
