The Joint Staff thanked the Pentagon’s top military planner for 32 years of service, and then took the thank-you back.
Defense Secretary Pete Hegseth has fired Army Lt. Gen. Brett Sylvia, the director of strategy, plans and policy for the Joint Chiefs of Staff, a defense official said Wednesday, Oct. 28, 2026. The official, who spoke on condition of anonymity to discuss a sensitive personnel matter, said no reason was given for the removal and that there is no immediate replacement. Sylvia is the second general pushed out of the post, known across the military as the J5, during Hegseth’s tenure.
Then the accounts split. A Pentagon official, also speaking anonymously, said Sylvia was accused of misconduct for allegedly leaking classified information about the Iran war and the Russia-Ukraine war, that he failed three polygraph tests about sharing classified material with the press, and that the case was referred to the Justice Department. Two other Pentagon sources said the firing was tied to the polygraph tests but said those accusations are not true.
The Thank-You That Was Taken Back
A spokesman for Joint Chiefs Chairman Gen. Dan Caine confirmed the ouster and, in a first statement, extended the chairman’s and the Joint Force’s gratitude to Sylvia and his family for 32 years of distinguished service, wishing them the best. The Joint Staff later withdrew it, saying it did not reflect the full circumstances, and a spokesperson declined to say more, citing the ongoing personnel process.
Chief Pentagon spokesman Sean Parnell addressed the matter on X on Thursday, Oct. 29, without naming Sylvia at all.
“Following an extensive Air Force OSI investigation, the Department took necessary personnel action to protect sensitive information,” Parnell wrote. He said nothing further would be said about the individual or the circumstances in order to protect the integrity of the investigation, and that the matter, along with others, had been referred to the Justice Department for possible legal action.
Sources cited in the first report of the firing said Hegseth had lost confidence in Sylvia amid tensions with Pentagon policy chief Elbridge Colby.
Fired as Trump Weighs New Strikes
President Donald Trump has repeatedly floated new military operations against Iran eight months into the war, and has said fresh strikes are an option after the Nov. 3 midterm elections. Two diplomats briefed on the matter said Washington has warned Middle East partners to brace for renewed U.S. action once the votes are counted, and for possible Iranian retaliation against them. Thousands more troops and a third U.S. carrier are on the way to the region. Trump has not made a final decision.
The J5 director and his staff typically generate and coordinate military plans with the chairman of the Joint Chiefs and the president. A Defense Department spokesperson said Sylvia’s termination was for severe misconduct and that he was not a central planner for the Iran war — that work, the spokesperson said, belongs to U.S. Central Command and its commander, Adm. Brad Cooper. Hegseth spent Wednesday, Oct. 28, in Cebu, central Philippines, at the ASEAN Defence Ministers’ Informal Meeting.
A Purge That Takes a Generation
Sylvia is the latest of nearly two dozen generals, admirals and other military leaders fired, forced to retire or otherwise pushed out under Hegseth, almost none of it publicly explained by the Pentagon. The group includes the civilian secretaries of the Army and Navy and top uniformed officers of the services. Sylvia’s predecessor in the J5 job, Lt. Gen. Joseph McGee, was forced to retire in October 2025.
Hegseth has ordered the military to double its cuts to the top officer corps — a 20 percent reduction by Jan. 1, 2027, from roughly 800 flag and general officer positions. At Marine Corps Base Quantico, Va., on Sept. 30, he told junior officers and enlisted leaders that he regards the cuts as accountability that is long overdue.
Some members of Congress have called the thinning of the general ranks a purge that will take years to rebuild. Sen. Mark Kelly, D-Ariz., a former Navy combat pilot and a critic of Hegseth, said the defense secretary appears to carry a deep-seated grievance about military leadership.
“He’s purging a generation of great leaders of the military, and it’s going to take a generation to recover from it,” Kelly said.
No successor has been named, and it is unclear who will take over Sylvia’s responsibilities. The investigation into the alleged disclosures remains open. Hegseth has made rooting out leakers a priority; high-ranking military officials were subjected to polygraph tests, according to reports in September, and three staffers from his own office were escorted out last year during a leak investigation whose results the Pentagon never released.
Sylvia commanded the 101st Airborne Division at Fort Campbell, Ky., until May 2025, and had earlier served as vice director of the J5. He served in Afghanistan and Iraq and was wounded during a 2013 combat mission in Afghanistan, earning a Bronze Star for Valor and a Purple Heart. His official biography has been taken offline.
