President Trump is slated to attend an unusual meeting of military leaders Tuesday in Virginia organized by Defense Secretary Pete Hegseth.

Last week, The Washington Post initially reported a significant meeting expected to convene numerous generals and admirals globally.

The Pentagon confirmed on Thursday that Hegseth is set to speak with senior military leaders, though they have not released further details about the discussion topics.

The sizable, impromptu nature of this gathering has led to speculation about the Defense Department’s motives for organizing such an event.

Here’s what we know so far about Tuesday’s meeting:

Where is the meeting?

The meeting will be organized at the Marine Corps base in Quantico, Va.

Who will be there?

Hundreds of military leaders are expected to attend.

Reportedly, nearly all top commanders worldwide, including those holding the rank of brigadier general or higher, their Navy counterparts, and top enlisted advisors — totaling over 800 senior officers — have been summoned.

These military leaders may be traveling from various regions, including conflict areas in the Middle East and Africa, as well as from the European and Indo-Pacific sectors, temporarily leaving their posts without their senior officers.

Trump will also be in attendance.

What precedent is there for such a large meeting?

Such a large in-person meeting of high-ranking officials at short notice is exceedingly rare, as even smaller gatherings usually require months of preparation.

While meetings of top military officials are not unusual, the sheer number of combatant commanders for this upcoming meeting has raised eyebrows, as has the limited information as to why it is taking place.  

Military leaders often rely on secure communications to meet remotely without leaving their bases, including during times of conflict. 

“We’re way out in terms of unusual in this one,” retired Army Lt. Gen. Mark Hertling, a former commanding general of U.S. Army Europe, said Friday on MSNBC’s “Morning Joe.”

What is the meeting about?

Trump on Sunday described the gathering to NBC News as “really just a very nice meeting talking about how well we’re doing militarily, talking about being in great shape, talking about a lot of good, positive things.”

“We have some great people coming in, and it’s just an esprit de corps. You know the expression ‘esprit de corps’?” Trump told the network in a phone interview. “That’s all it’s about. We’re talking about what we’re doing, what they’re doing, and how we’re doing.”

An official familiar with the plans previously told NBC the meeting was meant for Hegseth to highlight the military’s accomplishments and outline the future of the Defense Department under the Trump administration.

The Post reported Friday that the meeting is “meant to be an eyeball-to-eyeball kind of conversation” between Hegseth and his top officers, citing one person familiar with ongoing discussions.

Richard Haass, president emeritus of the Council on Foreign Relations, hypothesized that the meeting could be “a cultural thing,” with Hegseth wanting to “assert his authority.”

Active-duty colleagues “don’t know what this is about,” Hertling said. “So it could be about a shifting national security strategy, it could be cuts to the general officer corps — Secretary Hegseth has mentioned that several times — it could be about the upcoming budget stalemate, or it could be concerns over information leaks or press leaks.”

What has the White House said?

Trump and Vice President Vance downplayed reports about the meeting last week.

“It’s actually not unusual at all, and I think it’s odd that you guys have made it into such a big story,” Vance said.

“I think it’s great when generals and top people want to come to the United States to be with our now-secretary of War,” Trump said at the White House on Thursday, suggesting the generals would be “touring equipment sites” and “talking about the newest weapons.”
