Hegseth fires the Pentagon’s top military planner, Lt. Gen. Brett Sylvia, as Trump weighs new Iran strikes
Defense officials said Hegseth had lost confidence in Sylvia, who clashed with Elbridge Colby, in the latest exit of a senior officer.
Defense Secretary Pete Hegseth has fired the Pentagon’s top military planner, Army Lt. Gen. Brett Sylvia, a defense official said on Wednesday2,6. The move comes as President Donald Trump weighs new strikes against Iran2,4.
Hegseth and his team forced out the general, the latest step in a long-running purge at the top of the military, officials said1. Sylvia is another senior officer to leave, according to sources3. Sylvia was the Pentagon’s top planning officer4. He was the director of planning5, and was dismissed from the Joint Chiefs as its top military strategist9.

Why it matters to investors
The reasons given differ. Defense officials said Hegseth had lost confidence in Sylvia and that the general had clashed with Elbridge Colby, a top Pentagon official7. Another account said the general was accused of leaking classified Iran war information8.
The timing matters for markets watching the Iran war. The US military may be planning a return to war, but its director of planning is out5. Hegseth pushed out the top planning officer as renewed action against Iran looms4. Tankers are still under attack in the Strait of Hormuz, where a ship was reported on fire8.
The firing also adds to a pattern. Officials described it as the latest in a long-running purge of the Pentagon’s senior ranks1, and the general’s departure leaves Pentagon brass guessing7. The removal marks another senior officer to leave under Hegseth3.
What to watch
The first marker is who replaces Sylvia in the planning role, as the administration considers new Iran strikes2,4.
The second is the leak allegation. One report tied the firing to claims that the general leaked classified Iran war information8, while officials pointed to a loss of confidence and a clash with Colby7. Which account holds will shape how the move is read.
The third is Iran itself. Trump is considering new strikes2, and the dismissal of the top planner comes as the military weighs a return to war5. Any decision on renewed action would follow a change at the head of the office that plans it4,6.
The fourth is the Pentagon’s internal balance. Sylvia’s clash with Colby was one of the reasons defense officials gave for the firing7, and the purge of senior officers has run for months1.
