In a sweeping shakeup of the Pentagon’s leadership, President Donald Trump dismissed the nation’s highest-ranking military officer, replacing him with a retired Air Force general.
General Charles Q. “CQ” Brown Jr., the Chairman of the Joint Chiefs of Staff, was among several high-ranking military officials removed from their posts on Friday evening.
Trump made the announcement on his social media platform, Truth Social, where he thanked Brown for his service and leadership.
“He is a fine gentleman and an outstanding leader, and I wish a great future for him and his family,” Trump wrote. Brown’s term was originally set to end in 2027.
Here's What They're Not Telling You About Your Retirement
In the same post, Trump revealed his nominee to replace Brown: Lt. Gen. John Dan Caine. A former F-16 fighter pilot, Caine has held significant roles in military and national security circles, including as Associate Director for Military Affairs at the Central Intelligence Agency and as a National Guard member from 2009 to 2016. Caine retired in 2024.
“General Caine is an accomplished pilot, national security expert, successful entrepreneur, and a ‘warfighter’ with significant interagency and special operations experience,” Trump stated in his announcement.
Caine’s extensive combat and national security background includes serving with the 121st Fighter Squadron at Andrews Air Force Base on September 11, 2001.
He was among those who patrolled American airspace in the aftermath of the terrorist attacks. His military accolades include a Distinguished Flying Cross, an honor recognizing extraordinary aerial achievement.

Defense Secretary Pete Hegseth supported the move, acknowledging Brown’s contributions while endorsing Caine’s appointment. “General Brown has been a thoughtful advisor, and we thank him for his years of service,” Hegseth said in a statement. He further praised Caine, describing him as a leader who “embodies the warfighter ethos.”
Hegseth’s statement also confirmed additional leadership changes within the Pentagon, including the removal of Admiral Lisa Franchetti, Chief of Naval Operations, and General James Slife, Vice Chief of Staff of the Air Force.
“I am also requesting nominations for the positions of Chief of Naval Operations and Air Force Vice Chief of Staff,” Hegseth wrote. “The incumbents in these important roles, Admiral Lisa Franchetti and General James Slife, respectively, have had distinguished careers. We thank them for their service and dedication to our country.”
In addition to the high-profile dismissals, the Defense Department is actively seeking nominations for the Judge Advocates General positions—the top judicial roles in the Army, Navy, and Air Force.
General Brown’s tenure as Chairman of the Joint Chiefs of Staff began in 2023 under President Joe Biden. A former fighter pilot himself, Brown had been leading the U.S. Air Force since 2020 before stepping into the nation’s top military advisory role. On the day of his dismissal, he was visiting U.S. troops stationed at the southern border.
Trump’s decision to replace Brown and other senior officers signals a continued effort to reshape military leadership in alignment with his administration’s defense priorities.
His nomination of Caine underscores a preference for battle-tested, operationally focused leaders with direct experience in combat and national security strategy.
As the Pentagon awaits confirmation of Caine and the new leadership team, the changes mark a significant realignment within the highest echelons of the U.S. military.
Whether these shifts will lead to policy adjustments or operational changes remains to be seen, but the shake-up is sure to reverberate throughout the Department of War in the coming weeks.
