Lawmakers ask Army to explain why it told a military unit to stop specializing in drone warfare

WASHINGTON (AP) — A bipartisan group of U.S. lawmakers is pressing the Army to explain why it told a unit based in Europe to stop specializing in drone warfare , an order that comes as the world's battlefields rapidly evolve and military tactics increasingly rely on uncrewed systems to fight.

The 173rd Airborne Brigade was building its own drones and practicing the kind of warfare that Ukraine has pioneered against Russia and that Iran has fought against the U.S. — warfare that has killed and wounded American troops. The brigade of 600 soldiers was set up in November to be deployed anywhere that drones were needed.

"We have deep concerns that eliminating this specialized drone unit will limit our ability to learn from allies, particularly the Ukrainian Armed Forces, and hinder our efforts to modernize drone warfare at the speed necessary to compete on the modern battlefield," the lawmakers said in a letter shared with The Associated Press.

It requests a briefing from the Army to explain its decision and was sent Tuesday to departing Army Secretary Dan Driscoll and Gen. Christopher LaNeve, the Army’s acting chief of staff. It was signed by Democratic Sen. Jeanne Shaheen of New Hampshire, Republican Sen. Thom Tillis of North Carolina, independent Sen. Angus King of Maine and Republican Rep. Mike Turner of Ohio.

“This specialized unit was a prudent response in a moment when the character of warfare is changing faster than a conventional formation’s ability to adapt,” the lawmakers say.

They said they were particularly keen to understand the data, analysis and process behind the change after less than a year of the drone unit being active. They also want to know if the decision was based on guidance from Pentagon leadership or made internally by the Army.

LaNeve, who is filling in as the Army’s top uniformed officer, recently ordered the battalion to refocus on its core mission of being an airborne infantry unit. The move followed Defense Secretary Pete Hegseth’s sudden ousting of the Army’s prior chief of staff, Gen. Randy George.

Integrating drones into the Army’s tactics was a major focus for George. Last year, he and Driscoll had rolled out what they called the Army Transformation Initiative , which pushed to add “modernized (unmanned aircraft systems) into formations.”

George, who became Army chief of staff under President Joe Biden, regularly spoke about the need to accelerate development of new drone systems and get them in the hands of regular soldiers, not just specialized units. Driscoll supported such efforts and focused on cutting the red tape for military contractors to quickly develop more drones.

After George was ousted by Hegseth without explanation in April, he was replaced by LaNeve. This week, Driscoll submitted his own resignation, but a reason for his departure was not publicly revealed. He was an ally of George, and his tensions with Hegseth have been widely reported.

“We are supportive of the transformative initiatives the Army has taken under Secretary Driscoll’s leadership in this area and would like to see that momentum maintained even as uniformed leadership changes,” the lawmakers wrote.
