Pentagon Purge: US Army Secretary Dan Driscoll Steps Down After 18 Months

US Army Secretary Dan Driscoll reportedly submitted his resignation to President Donald Trump after roughly 18 months in office, the White House confirmed on Monday, marking the latest high-profile exit amidst reported rift between political appointees and military leadership at the Pentagon.

The White House provided no specific official reasons for the 41-year-old top civilian official’s sudden exit. However, media reports indicate that Driscoll tendered his resignation following months of behind-the-scenes friction with Defence Secretary Pete Hegseth.

Driscoll spoke directly with President Trump on the current state of the force before handing in his papers, according to an Army official reportedly speaking on condition of anonymity.

While confirming the development, White House spokeswoman Anna Kelly praised the outgoing official. "Secretary Driscoll has been reportedly highly effective in advancing President Trump's agenda to Make America Strong Again at the Department of the Army by providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more," Kelly stated, adding that the force is "more powerful than ever".

Leadership Vacuum at the Pentagon

In April, Navy Secretary John Phelan abruptly resigned. Since taking charge, Hegseth has reportedly removed or forced out over a dozen senior military commanders, including the Chief of Naval Operations and the Air Force’s Vice Chief of Staff.

The Army has faced severe disruption. Hegseth ousted the service's top uniformed officer, Gen Randy George, alongside Gen David Hodne and Maj Gen William Green. In June, Gen Christopher Donahue, head of US Army forces in Europe and Africa, also unexpectedly stepped down.

Driscoll, a close ally of Gen George, lamented his removal in April, revealing to lawmakers that he and his family drove to George's home following the resignation to offer support. Driscoll noted at the time that while the situation was difficult, civilian leadership retains the authority to choose its desired leaders.

Rollback of Modernisation and Drones

Driscoll, an Iraq War veteran and former cavalry platoon leader, earned the moniker of Trump’s "drone guy" due to his aggressive push to incorporate emerging battlefield technologies and low-cost unmanned platforms.

However, the modernising strategies championed by Driscoll have reportedly faced reversals. Following Gen George’s departure, Gen Christopher LaNeve, a fast-rising officer under Hegseth took over as acting chief of staff. Under LaNeve's direction, the service pulled the plug on a major drone modernisation project, instructing an operational unit in Europe to cease its custom drone manufacturing and revert to a standard infantry role.

Driscoll, a Yale Law School alumnus and close ally of Vice President JD Vance, drew bipartisan praise. While Republican leaders highlighted his discipline, Democratic lawmakers warned that his exit leaves the Pentagon leadership increasingly "rudderless".
