Pentagon official says the plan will be announced in the defence secretary’s ‘State of the Force’ address in Virginia.

United States Defense Secretary Pete Hegseth will cut the number of positions reserved for generals and admirals by 20 percent, a Pentagon official has told Al Jazeera, in a change that will affect leadership across the Army, Navy and Air Force.

Hegseth is expected to announce the decision on Wednesday during a visit to the Marine Corps Base Quantico in Virginia, where he will deliver his “State of the Force” address in front of junior officers and enlisted officials, the official said.

Media outlets in the US have also reported on the move.

The Associated Press news agency, citing Pentagon officials, reported that Hegseth will direct all the military services to double the 10 percent reduction that he ordered last year to the roughly 800 flag and general officer positions. This would make it a 20 percent total decrease and is to be completed by January 1, 2027.

Fox News reported the new reductions could include any one-star general or above or officer of equivalent Navy rank.

The Washing Post reported that the cuts could affect the careers of “hundreds of current and rising military leaders following scores of firings and denied promotions”.

US President Donald Trump or Hegseth have fired, or pushed into retirement, more than two dozen military leaders since taking office in January 2025, including the Army’s top uniformed officer, General Randy George, in April.

The administration also fired the only two women serving as four-star officers, along with several other senior female officers. Other top officials have left through retirements and resignations, including the Army secretary, Dan Driscoll, who resigned this month after repeated clashes with Hegseth.

When the defence secretary first announced the effort to trim the highest levels of the military ranks, he argued it was intended to remove “redundant force structure to optimise and streamline leadership”. And in a memo released in May 2025, he added that his aim was to free the military from “unnecessary bureaucratic layers”.

At this time last year, Hegseth also declared an end to “woke” culture and announced new directives for troops that included “gender-neutral” or “male-level” standards for physical fitness.

Senator Jack Reed, a Rhode Island Democrat and ranking member of the Senate Armed Services Committee, expressed concern over Hegseth’s latest move in a statement. He said eliminating senior leadership positions must be done in consultation with Congress and warned that the planned cuts “should alarm every American”.

“Congress has been clear with the Secretary that he must consult this body and explain his reasoning for senior officer removals and promotion holds. To date, we have not received satisfactory answers,” Reed said.

“Our military is conducting major operations around the world, and the force is already under strain,” he added.

The number of general officer positions is set by law, but positions can be left unfilled if the administration does not submit nominees to Congress.
