Pentagon Reports 140 US Troops Wounded in Iran War, 8 Severely

On March 10, 2026, as bombers thundered east for what Defense Secretary Pete Hegseth called the "most intense day of strikes inside Iran" since the war began [1], the Pentagon quietly released a number that brought the conflict's toll into sharper focus: approximately 140 U.S. service members have been wounded in just ten days of fighting, with eight classified as severely injured [2].

The figure is the first comprehensive injury count since Operation Epic Fury began on February 28, and it arrives amid an expanding regional conflagration that has killed more than 1,200 people in Iran, shuttered the Strait of Hormuz, sent oil prices past $100 a barrel, and triggered the largest antiwar protests in the United States since the Iraq War era [3][4].

The Casualty Picture

According to the Pentagon briefing delivered by Hegseth and Chairman of the Joint Chiefs Gen. Dan Caine, the vast majority of the 140 injuries have been classified as minor, and 108 service members have already returned to duty [2]. The injuries stem primarily from Iranian retaliatory rocket and drone strikes targeting U.S. military installations in the Persian Gulf region.

But the headline number obscures a grimmer reality. Eight U.S. service members have died in connection with the conflict. Six were killed in a single devastating Iranian drone strike on a makeshift operations center at the civilian port of Shuaiba in Kuwait on March 1 — an attack that came, survivors told CNN, with "no warning, no siren" [5]. The dead included Captain Cody A. Khork, 35; Sergeant First Class Noah L. Tietjens, 42; Sergeant First Class Nicole M. Amor, 39; and Sergeant Declan J. Coady, 20, all assigned to the 103rd Sustainment Command, an Army Reserve unit from Iowa [6]. A seventh service member, an Army sergeant wounded in a separate attack in Saudi Arabia on March 1, succumbed to injuries on March 8 [7]. An eighth soldier died from a health-related incident in Kuwait on March 6.

The eight severely wounded service members "are receiving the highest level of medical care," Hegseth said, without providing further details on the nature of their injuries [2].

How the War Began

The conflict traces its origins to three rounds of failed diplomatic talks between Washington and Tehran. The first took place on February 6 in Muscat, Oman, with U.S. Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi representing their respective governments. A second round in Geneva on February 17 produced draft proposals. The third convened on February 26, also in Geneva, combining indirect Omani-mediated negotiations with direct talks [8].

When Iran rejected what the White House described as a final offer — a joint civilian nuclear program in exchange for permanently dismantling enrichment facilities — President Trump declared that Tehran had "refused to say yes to peace" [9]. Two days later, midmorning on February 28, U.S. and Israeli forces launched nearly 900 strikes in the first 12 hours, targeting Iranian missile defenses, military infrastructure, leadership compounds, and nuclear facilities [10].

Supreme Leader Ali Khamenei was killed in the first wave, along with dozens of senior Iranian officials [10]. President Trump outlined four objectives for the campaign on TruthSocial: preventing Iran from acquiring a nuclear weapon, destroying its missile arsenal and production sites, degrading its proxy networks, and annihilating its navy [11].

Iran's Retaliation and the Expanding Battlefield

Iran's response was swift and massive. By March 5, Iranian forces had fired over 500 ballistic and naval missiles and nearly 2,000 drones, with approximately 40 percent directed at Israel and 60 percent at U.S. targets across the Gulf [10]. The Interim Leadership Council, established on March 1 under Iran's constitutional succession provisions, signaled that the fight would continue. Mojtaba Khamenei, son of the slain supreme leader, was elected as the new Supreme Leader on March 8 [12].

The battlefield expanded rapidly beyond Iran's borders. On March 1 and 2, U.S. and Israeli forces struck Iranian-backed Iraqi militias [10]. On March 4, a U.S. submarine sank the IRIS Dena, Iran's most modern frigate, 40 nautical miles off Sri Lanka's southern coast — a confrontation far from the Middle East that signaled the conflict's broadening geographic scope [13]. Israel conducted extensive air campaigns in Lebanon, where at least 486 people have been killed [3]. Houthi-controlled Yemen announced it would resume attacks on commercial shipping in the Red Sea [14].

By March 10, Hegseth reported that Iranian missile attacks had fallen 90 percent and one-way attack drones had decreased 83 percent since the war began — a metric the Pentagon cited as evidence of degraded Iranian capability [1].

The Human Toll Beyond U.S. Forces

The casualty figures on the Iranian side remain contested and far larger. Iran's deputy health minister, Ali Jafarian, reported at least 1,255 killed, including 200 children and 11 healthcare workers, with more than 12,000 wounded [15]. The Hengaw Organization for Human Rights, a Kurdish monitoring group, put the figure dramatically higher at 4,300 dead in the first ten days, with 390 civilians — 9.6 percent of the total — and 3,910 members of Iranian military forces [16]. Satellite imagery has confirmed damage to the Natanz nuclear facility, the Iran Atomic Energy Agency headquarters in Tehran, and the Parchin explosive research testing facility [11].

At least 13 Israelis have been killed and 1,929 wounded in Iranian retaliatory strikes on Israeli territory [3].

The Strait of Hormuz and the Global Economic Shockwave

Perhaps the war's most far-reaching consequence has been the near-total shutdown of the Strait of Hormuz, through which more than 20 percent of the world's daily oil supply typically flows. The Islamic Revolutionary Guard Corps issued warnings prohibiting vessel passage, and subsequent attacks on ships caused tanker traffic to plummet by 90 percent in the first week [14]. On March 1 and 2, no ships transited the strait at all [17].

The disruption cascaded through global markets with stunning speed. Oil prices surged past $100 per barrel — Brent crude touching $104 — for the first time since Russia's 2022 invasion of Ukraine [18]. Analysts warned prices could reach $150 per barrel by month's end if Hormuz traffic doesn't resume [19]. Gas giant QatarEnergy, responsible for 20 percent of global LNG supply, declared force majeure on all shipments on March 4 [14].

Stock markets reeled. South Korea's KOSPI index suffered its worst single-day crash since the 2008 financial crisis, dropping 12 percent [19]. Dow futures sank 1,000 points on March 8 [20]. The disruption extends far beyond energy: up to 30 percent of the world's fertilizer exports pass through Hormuz, threatening food prices globally at a time when supply chains were already strained [21].

Media Coverage Intensity

Global media coverage of the conflict spiked dramatically on February 28 — the day strikes began — and has remained elevated throughout the first ten days of war. Data from the GDELT Project, which monitors worldwide news coverage in real time, shows that media attention to the "Iran war troops" topic surged more than 20-fold on the day of the initial strikes compared to the prior week, and has sustained levels roughly ten times pre-war baseline throughout early March [22].

A Divided Nation at Home

The war is already deeply unpopular with the American public. An NPR/PBS News/Marist poll found that 56 percent of Americans oppose the conflict [23]. More strikingly, 55 percent said Iran did not pose an imminent threat to the United States, 59 percent believed the president should have sought congressional approval, and 62 percent concluded the administration had not clearly explained its rationale for military action [23].

Congress has fractured largely along party lines. Senator Bernie Sanders called the campaign "unconstitutional" and a violation of international law, demanding Congress "pass a War Powers Resolution immediately" [24]. The House voted on the bipartisan Khanna-Massie Iran War Powers Resolution on March 5, while the Senate considered the Kaine-Paul version around March 4 [24].

Antiwar protests erupted in cities across the country on February 28 and have continued since. But the domestic picture is more complicated than simple opposition. In San Francisco, as hundreds rallied against the strikes at the Ferry Building, a group of Iranian-Americans staged a counterprotest — waving Lion and Sun flags, dancing, and cheering the campaign against the Islamic Republic [25].

What Comes Next

The trajectory of the conflict remains deeply uncertain. On March 10, Trump sent contradictory signals about the war's future, telling CBS News "I think the war is very complete, pretty much," while later saying "We've already won in many ways, but we haven't won enough" and pledging to "go forward more determined than ever" [26]. His stated condition for ending the conflict — Iran's "unconditional surrender" — appears nowhere close to being met [9].

Iran's foreign minister Araghchi has flatly rejected negotiations, saying talks with Washington would not "be on the table" again [27]. Iran's parliamentary speaker declared, "Certainly we aren't seeking a ceasefire" [27]. Iranian President Masoud Pezeshkian has acknowledged that "some countries" have begun mediation efforts, without identifying them [27].

Meanwhile, the Pentagon's casualty figures — 140 wounded, eight dead — represent the sanitized tip of a far larger iceberg. Iran claims 400 kilograms of 60 percent enriched uranium remains hidden at an undisclosed location [11]. The Strait of Hormuz remains functionally closed. Oil prices continue to climb. And as Hegseth promised "the most intense day of strikes" yet, the question looming over Washington, Tehran, and world capitals is not just how the war ends, but what the region and the global economy look like when it does.

PBS News observed that Hegseth's carefully worded casualty briefing reflected "the government's reluctance to show human costs of war" — a pattern familiar from prior American conflicts [28]. The 140 wounded service members, their names and stories largely unknown to the public, embody a truth that numbers alone cannot capture: the cost of war is always, in the end, measured in human beings.
