Pentagon removes top planner as Trump weighs new Iran strikes

Defense Secretary Pete Hegseth dismissed Army Lt. Gen. Brett Sylvia from his post as the Pentagon’s top military planner on Wednesday. This action removes the officer responsible for coordinating strategy with the president and the Joint Chiefs during an active conflict. The departure leaves the position, known as the J5, vacant with no immediate successor named.

Sylvia is the second general to lose this specific role under Hegseth. His predecessor, Lt. Gen. Joseph McGee, was forced into retirement in October 2025. A defense official, speaking on condition of anonymity regarding sensitive personnel matters, confirmed the firing and stated that the Pentagon has not provided a public reason for Sylvia’s removal. The change was first reported by The Atlantic.

The dismissal occurs while President Donald Trump considers launching new military strikes on Iran. The war, which began eight months ago with Israel’s entry into the conflict, has not ended. Trump has indicated that new operations are possible after the midterm elections scheduled for next week. He has vowed to finish the job in the region.

U.S. officials have alerted several Middle East countries and regional allies to prepare for potential renewed U.S. military action. These officials also warned that Iran may attempt to retaliate against those nations. Two diplomats briefed on the matter said Trump has not yet made a final decision on new strikes. Currently, a third U.S. aircraft carrier and thousands of additional troops are moving into the region.

Sylvia had served as commander of the 101st Airborne Division at Fort Campbell, Kentucky, until May 2025. His official biography on the Joint Staff website has been taken offline. Before that role, he served as the vice director for the J5. A spokesperson for the Joint Staff thanked Sylvia and his family for 32 years of service in a brief statement.

This firing is part of a wider reduction in senior military leadership under Hegseth. Nearly two dozen generals, admirals, and other leaders have been fired, forced to retire, or have departed during his tenure. Most of these departures have not been publicly explained. The cuts also include civilian secretaries of the Army and Navy.

Hegseth ordered the military to cut the number of top officers by 20% by January 1, 2027. There are currently roughly 800 flag and general officer positions. He described the reduction as a long-overdue measure of accountability. Senator Mark Kelly, D-Ariz., criticized the process last month, calling it a purge that will take a generation to recover from.

The Pentagon did not respond to messages seeking comment late Wednesday. Sylvia’s removal leaves a gap in the command chain at a time when military planning for the Iran conflict is intensifying. The J5 office typically generates the strategic plans that guide the armed forces in coordination with the president.
