Hegseth Removes J5 Planner as Trump Weighs Iran Strikes

Defense Secretary Pete Hegseth has dismissed the Pentagon's chief military planner, a move that leaves the highest-ranking strategic office vacant while President Donald Trump considers new attacks on Iran. Army Lt. Gen. Brett Sylvia was removed as the head of strategy, plans, and policy on the Joint Chiefs of Staff, a position known in military circles as the J5. A defense official speaking on condition of anonymity confirmed the dismissal on Wednesday, noting that no immediate replacement has been named and no public reason was provided for the decision.

Sylvia is the second general to lose the J5 post under Hegseth. His predecessor, Lt. Gen. Joseph McGee, was forced to retire in October of last year. The Joint Staff spokesperson expressed gratitude to Sylvia and his family for 32 years of service, wishing them the best. The official biography for Sylvia, which detailed his previous command of the 101st Airborne Division at Fort Campbell, Kentucky, until May 2025, has been taken offline from the website.

The personnel change arrives at a tense moment in the eight-month conflict with Iran. Trump has stated he intends to finish the job in Iran and has suggested that new military operations are an option following the midterm elections scheduled for next week. U.S. officials have briefed several Middle East countries and regional allies to prepare for potential renewed action, as well as for possible Iranian retaliation. Two diplomats briefed on the matter said Trump has not yet made a final decision on new strikes.

Military assets are already shifting toward the region. A third U.S. aircraft carrier and thousands of additional troops are en route. The J5 director and staff are typically responsible for generating and coordinating military plans with the chairman of the Joint Chiefs and the president. Sylvia had previously served as the vice director for the J5 before assuming the top role.

Sylvia's departure is part of a wider pattern of leadership turnover. Nearly two dozen generals, admirals, and other military leaders have been fired, forced to retire, or have departed under Hegseth's tenure. Almost none of these departures have been publicly explained by the Pentagon. The group includes the civilian secretaries of the Army and Navy as well as top uniformed officers for the military services. The Pentagon did not immediately respond to messages seeking comment late Wednesday.

Hegseth ordered the military to double cuts to the overall number of top officers in September. The goal is a 20 percent decrease to be completed by Jan. 1, 2027. There are currently roughly 800 flag and general officer positions. Hegseth described the cuts as accountability that was long overdue when he spoke to junior officers and enlisted leaders at Marine Corps Base Quantico on Sept. 30. Sen. Mark Kelly, D-Ariz., a former Navy combat pilot, criticized the reductions as a purge that will take years to rebuild. He said Hegseth has a deep-seated grievance about military leadership and is purging a generation of great leaders.
