United States President Donald Trump has hinted at immediate leadership changes within the military, just hours before addressing hundreds of generals and admirals in a highly unusual closed-door summit at Marine Corps Base Quantico.

In remarks made outside the White House on Tuesday, September 30, just hours before the meeting, Trump said he planned to assess senior military figures personally and did not rule out dismissals based on those encounters.

“The military in my first term, we had a great first term. We had the greatest economy ever. I’m going to be meeting with generals and with admirals and with leaders — and if I don’t like somebody, I’m going to fire them right on the spot,” the president said during a media interaction.

Although White House officials, including Vice President JD Vance, have attempted to downplay the significance of the summit — describing it as a “routine” gathering — experts and military observers have expressed concern over its scale, secrecy, and tone.

Behind the auditorium stage where Trump and Defense Secretary Pete Hegseth are scheduled to speak, a massive American flag serves as a backdrop, flanked by banners reading “Strength, Service, America” and the flags of the U.S. armed services.

Trump, who confirmed his attendance earlier in the week, had initially described the meeting as a positive opportunity to “talk about how well we’re doing militarily,” adding that it would help build “esprit de corps” among the ranks.

More than 800 high-ranking military officers have reportedly been summoned to the Virginia base — including generals, admirals, and top enlisted personnel from global U.S. military installations in Europe, the Middle East, and East Asia. Attendees began arriving hours before the event, dressed in formal uniforms representing their respective service branches: Army, Navy, Air Force, Marine Corps, and Space Force.

Many wore campaign medals from past deployments, with notable representation from veterans of the Afghanistan and Iraq wars, as well as operations linked to the broader U.S. war on terror following the attacks of September 11, 2001.

The gathering is remarkable not only for its scale, but also for its in-person nature — especially in an era where virtual briefings are the norm. Analysts have questioned the decision to bring so many senior officers together physically, citing both security risks and logistical burdens.

“It is mystifying why this was not done virtually so that senior officers don’t have to spend a lot of time travelling,” Mark Cancian of the Center for Strategic and International Studies think tank told Reuters.

Admiral Giuseppe Cavo Dragone, chair of NATO’s Military Committee, was quoted by the AP news agency saying that “as far as my 49 years of service, I’ve never seen that before.”

Defense Secretary Pete Hegseth, a key figure behind the event, has consistently advocated for reviving what he calls a “warrior ethos” across the armed forces. Since taking office, Hegseth has made headlines for rebranding the Department of Defense as the Department of War, arguing that the change better reflects the institution’s core mission and mindset.

This summit, according to some close observers, may be part of a broader strategy by Hegseth to reassert combat-focused values within the military hierarchy — and potentially to install leaders more aligned with that philosophy.

As of this morning, no personnel changes had been confirmed, but several insiders suggest the mood among senior officers is tense, given the unpredictability surrounding both the agenda and the president’s recent remarks.

The event is currently underway at the 55,000-acre Quantico base, under extremely tight security.
