WaPo (“More U.S. troops have died amid Iran war than Pentagon has disclosed publicly“):
More American service members have died in the Middle East during the ongoing Iran war than the Pentagon has disclosed publicly, according to six U.S. officials familiar with the Defense Department’s internal casualty accounting data.
Five of the officials said there have been at least 22 military fatalities — four more than what appears in the Pentagon’s public database, known as the Defense Casualty Analysis System, or DCAS.
A sixth official, who like the others spoke on the condition of anonymity to discuss the figures, said 23 service members have died since Feb. 28, when the Trump administration, in concert with Israel, initiated the Iran war. Not all of the undisclosed deaths are directly tied to the conflict but have involved U.S. personnel who were in the Middle East amid ongoing hostilities, this person said.
Additionally, the official said, three U.S. contractors who were based in the region have died since combat operations began.
As of Friday, the Pentagon’s DCAS database lists 18 U.S. military fatalities, including deaths caused by hostile and nonhostile action dating to the start of the Iran conflict.
Details surrounding the undisclosed deaths — including the service members’ identities, as well as when, how and where they died — remain unclear. Officials familiar with the higher casualty number expressed frustration that the additional loss of life is not reflected in the Pentagon’s public casualty portal.
DCAS is ostensibly updated every working day. Every page I’ve reviewed says “As of September 18, 2026.”
The Iran war is officially Operation Epic Fury (OEFU to distinguish it from Operation Enduring Freedom, the 7 October 2001-31 December 2014 Afghanistan campaign). The page for OEFU lists seven hostile casualties (all Army) and seven non-hostile (six Air Force and one Navy).
As noted in my July post “Iran War Casualty Count Surpasses 600,” the database seems intentionally confusing. It breaks down conflicts that even those of us who study these things professionally consider a single conflict, such as the Afghanistan and Iraq Wars, into multiple named operations. And all of the operations formerly lumped into the broader “Global War on Terror” rubric have since been redesignated “Overseas Contingency Operations (OCO).”
These are not to be confused with Overseas Operations (OO), which are defined as “Overseas operations casualties starting July 7th 2026.” Which operations might those be, you might ask? Don’t ask. Regardless, four service members, all from the Army, have been killed in them.
Combined, then, fourteen personnel from OEFU and four from OO makes eighteen.
Where are the other four or five? Damned if I can find them in DCAS. Which, again, was ostensibly updated yesterday. So, unless they all died in the last couple of days and we simply haven’t notified the next of kin yet, failing to account from them in the database is highly problematic.
