Defense Secretary Pete Hegseth awarded an Army sentinel the Joint Service Commendation Medal on Thursday, a day after the soldier told Hegseth's Veterans Day party at the Tomb of the Unknown Soldier to keep silence and respect².

Video from a network pool camera at Arlington National Cemetery on Wednesday showed Hegseth, his wife Jennifer Hegseth and aides posing for photographs on the steps in front of the tomb after President Donald Trump's wreath-laying^1,3,4.

Around 12:30 p.m., as the group broke up, someone was heard laughing, and the sentinel on duty turned and told the visitors, "All visitors will maintain an atmosphere of silence and respect at all times"³.

CBS News identified chief of staff Ricky Buria among those present; DC News Now, carrying The Hill, also named deputy chief of staff Patrick Weaver and senior adviser Tami Radabaugh^1,2.

Pentagon spokesman Sean Parnell said the secretary and the department honor military sacrifices and that a soldier correctly reminded everyone to maintain decorum^2,3.

A Pentagon official told The Hill that Hegseth hosted the 3rd U.S. Infantry Regiment, the Old Guard, at the Pentagon on Thursday and awarded Specialist Thomas Iglesias the medal for the execution of his duties at the tomb².

Euronews and the BBC described the same video of photographs, laughter and a shouted reminder after the ceremony; Al Jazeera carried Associated Press copy of the rebuke^4,5,6.

Outlets differ on emphasis: ABC News and Euronews lead with the laughter after the photo, while DC News Now leads with the medal^2,3,4. It is not independently established from these reports who laughed or whether Hegseth himself made the noise^3,4.
