Well it aligns with what the “people familiar with the matter, who spoke on the condition of anonymity” said in the article itself. I think it’s safe to say it’s unprecedented.

Top commanders in conflict zones and senior military leaders stationed throughout Europe, the Middle East and the Asia-Pacific region are among those expected to attend Hegseth’s meeting, said people familiar with the matter, who spoke on the condition of anonymity as they were not authorized to publicly discuss the issue. The order does not apply to top military officers who hold staff positions.

None of the people who spoke with The Post could recall a defense secretary ever ordering so many of the military’s generals and admirals to assemble like this. Several said it raised security concerns.

“People are very concerned. They have no idea what it means,” one person said.

Two others expressed frustration that even many commanders stationed overseas will be required to attend. One said, this is “not how this is done.”

“You don’t call GOFOs leading their people and the global force into an auditorium outside D.C. and not tell them why/what the topic or agenda is,” this person said, using an abbreviation for general officer or flag officer.

“Are we taking every general and flag officer out of the Pacific right now?” one U.S. official said. “All of it is weird.”
