In the immediate aftermath of the attacks, official Pentagon statements claimed that no US service members had sustained serious injuries, and that fewer than five personnel reported minor, superficial symptoms that were treated on site with no need for medical evacuation. However, exclusive reports from multiple national security outlets citing leaked internal Defense Department records and anonymous senior defense officials confirmed earlier this week that the actual number of injured troops is at least 47, with over 30 of those cases diagnosed with moderate to severe traumatic brain injury (TBI), a condition that often requires long-term neurological care and can cause permanent cognitive impairment. 12 of the injured personnel have been transferred to the US military’s Landstuhl Regional Medical Center in Germany for advanced treatment, while another 8 have been flown back to the contiguous United States for ongoing care, details that were deliberately omitted from all public Pentagon updates for 11 days after the attacks. Multiple congressional sources from both parties have stated that the Pentagon also failed to disclose the full casualty numbers to relevant House and Senate Armed Services Committee members in classified briefings held in the days after the strikes, prompting bipartisan calls for a formal investigation into the cover-up. Defense analysts note that the decision to hide the extent of troop injuries appears rooted in two core concerns: first, avoiding public backlash that would pressure the Biden administration to launch large-scale retaliatory strikes against Iran that could trigger a full-scale regional war, and second, avoiding criticism of the administration’s Middle East policy that has left US troops stationed in vulnerable, underprotected outposts across Iraq and Syria with no clear operational mandate. The Pentagon has since issued a revised statement acknowledging the higher casualty count, claiming that the delay was due to “the slow process of diagnosing and reporting TBI cases” rather than a deliberate cover-up, a claim that has been widely dismissed by both lawmakers and military veterans’ advocacy groups. Veteran organizations have pointed to a decades-long pattern of the Pentagon underreporting TBI cases in conflict zones to minimize public scrutiny of overseas military operations, and are demanding formal compensation for the affected troops and disciplinary action for officials who approved the delayed disclosure.
