WASHINGTON: The Pentagon has launched a lie-detector dragnet to comb through high-ranking military officials and identify who leaked information about US munitions stockpiles, according to US press reports.

In July, reports emerged that the Un­­­i­­ted States was rationing munitions — its missile interceptors, in pa­­­­­r­­ticular — over supply concerns after several months of fighting Iran.

Administration officials vehemently denied those reports, with President Donald Trump saying “we have a lot of ammunition, different types,” while acknowledging that “for some of the more sophisticated stuff, we’d certainly like to have more.”

Late on Friday, The New York Times reported that some 50 members of the military’s Joint Staff — the Pentagon’s planning and advisory staff — were being required to take polygraph tests as part of an investigation into how classified stockpile information made its way into journalists’ hands.

CBS News later also reported the wide-scale use of lie detectors, while adding that the chairman of the Joint Chiefs of Staff, General Dan Caine, had not been tested.

Both outlets cited unnamed officials. Asked about the reports, the Pentagon’s chief spokesman, Sean Parnell, refused to comment on “internal personnel or investigative matters,” but said that it “takes all leaks of classified national security information extremely seriously and investigates accordingly.”

“Securing classified information is critical to ensuring the security of the United States and of our troops deployed around the world,” Parnell added. Both the Times and CBS noted the scale of the polygraph testing.

Lie-detection testing is routine during background screenings and security clearance renewals for government staff with access to the most sensitive state secrets. But the wide-scale deployment of the detectors as part of a leak investigation was rare, if unprecedented, the outlets reported, citing analysts and unnamed officials.

Ammunition stockpiles leaks

The Pentagon launched an unprecedented investigation subjecting roughly 50 senior military officers and civilian employees to polygraph tests following media leaks regarding depleted US ammunition stockpiles from military conflict with Iran.

The inquiry, which critics characterise as an intimidation tactic engineered by Defence Secretary Pete Hegseth, aligns with broader Department of Defence initiatives to enforce stricter informational controls.

The Department of Defence launched an extensive internal investigation, subjecting senior military officers and civilian personnel on the Joint Staff to polygraph examinations following unauthorised disclosures regarding dwindling US munition stockpiles.

Rather than relying on the Federal Bureau of Investigation, Defence Secretary Pete Hegseth utilised the military’s internal investigative assets to execute the sweep, reflecting an institutional shift toward a more aggressive counterintelligence posture.

This probe followed the establishment of a joint task force between the Pentagon and the Justice Department designed to aggressively identify and prosecute suspected leakers.
