More than 600 US military personnel injured since Iran War began in February

At least 624 US military service members have been wounded since President Donald Trump ordered strikes against Iran in February, according to the Pentagon’s most recent update on 25 July.

The Defense Casualty Analysis System (DCAS) now separates the figures into two categories.

Operation Epic Fury, the name for the initial phase of operations that began around 28 February accounts for 14 killed and 417 wounded.

A newer “Overseas Operations” category, covering casualties starting 7 July when a fragile ceasefire began unraveling and fighting escalated, lists 4 killed and 207 wounded.

Combined, these total 18 US service members killed and 624 wounded since the conflict began.

The weekend update followed controversy over earlier downward revisions.

As recently as the prior week, the system had shown higher totals around 18 killed and 482 wounded before the numbers dropped, prompting questions from lawmakers including a letter from 12 Democratic members of the Senate Armed Services Committee to Defense Secretary Pete Hegseth and media scrutiny about transparency.

Pentagon officials attributed some fluctuations to temporary data disruptions.

Chief Pentagon spokesperson Sean Parnell had previously indicated nearly 100 service members sustained some degree of injury since 7 July, with the vast majority described as minor often concussions and most returning to duty.

The conflict began with joint US-Israeli strikes in late February.

A ceasefire was announced in April with a later memorandum of understanding in June, but hostilities resumed after Iranian actions involving vessels in the Strait of Hormuz around 7 July.

This led to nearly two weeks of intensified exchanges, including Iranian strikes on bases hosting US forces in the region (such as in Jordan and Iraq) that caused the recent fatalities and additional injuries.

A pause in the fighting has held since late last week.

The new accounting method and higher wounded total have drawn further attention to how the human cost of the war is tracked and reported, amid ongoing debates over the administration’s interpretation of War Powers timelines and the overall conduct of the campaign.
