The U.S. Army has completed its review of the deadliest Iranian attack on American troops in the Iran war, shifting part of the crisis from battlefield escalation to accountability for what happened at Kuwait’s Port of Shuaiba.

The new angle is not another strike claim or another fragile talks update. It is the Army’s internal review of the March 1 attack that killed six U.S. service members at a tactical operations center in Kuwait, a case that has already drawn questions from survivors, lawmakers, and families about force protection before the Iranian drone and missile assault.

CBS News reported Thursday that the Army had completed its investigation and that Gold Star families were expected to be briefed on the findings. Later, an Army spokesperson told CBS that officials had met privately with the families of those killed, but would not provide more details out of respect for the families and to protect the integrity of the discussions.

Anadolu Agency also reported that the Pentagon-ordered review examined the Iranian strike on the Port of Shuaiba site, citing CBS News. Anadolu noted that the attack remains the deadliest single strike on U.S. troops during the war and came as Iran launched missile and drone attacks on U.S.-allied Gulf states after Operation Epic Fury began.

What The Review Is About

The review was ordered by U.S. Army Central and Third Army to determine the facts and circumstances of the attack. CBS reported that six Americans were killed when the Port of Shuaiba tactical operations center was hit during the early phase of the U.S.-Israel war against Iran.

The Guardian reported in March that the U.S. Department of Defense identified the fallen service members as Capt. Cody A. Khork, Sgt. 1st Class Nicole M. Amor, Sgt. Declan J. Coady, Sgt. 1st Class Noah L. Tietjens, Maj. Jeffrey R. O’Brien, and Chief Warrant Officer 3 Robert M. Marzan. The Guardian said they were assigned to the 103rd Sustainment Command in Des Moines, Iowa, and were supporting Operation Epic Fury.

The attack was already politically sensitive because it came almost immediately after President Donald Trump said the administration was taking every possible step to reduce risk to U.S. personnel in the region. Since then, the Port of Shuaiba strike has become a test case for how prepared U.S. forces were for Iranian drones and whether military leaders properly acted on warning signs.

Survivors Alleged Force Protection Failures

CBS reported that several survivors described “strategic failures” before, during, and after the strike. One injured soldier told CBS in April that describing the Iranian drone as something that slipped through a fortified defense was false, saying the unit was not prepared to defend itself and was not in a fortified position.

According to CBS, multiple witnesses said there had been force-protection warnings before the unit moved to Port of Shuaiba. One senior official told the outlet that the troops had moved closer to Iran and into a deeply unsafe area that was a known target. CBS also reported that soldiers said intelligence had identified the position as a possible Iranian target.

The Pentagon has pushed back on claims that the incident was downplayed. CBS reported that Pentagon spokesperson Sean Parnell previously said every possible measure had been taken to protect troops and that the secure facility had six-foot walls.

That disagreement matters because the public has not yet seen the Army’s conclusions. The family briefings confirm the review is no longer theoretical, but they do not yet answer whether commanders, intelligence officers, or planners will face formal accountability.

Congress Had Already Demanded Answers

The Army review also lands after lawmakers pressed the Pentagon for answers. In a congressional letter posted by Rep. Pat Ryan’s office, Ryan and other House Democratic veterans demanded an investigation into what they called possible force-protection failures that led to the deaths of six service members in Kuwait.

The lawmakers cited CBS reporting and argued that the attack raised broader questions about Iranian drone threats to U.S. troops and assets across the region. Their letter asked Defense Secretary Pete Hegseth for a transparent investigation into the site of the attack and the wider implications for U.S. forces.

That pressure is likely to continue if the Army keeps the findings private. Family briefings are one step, but public accountability is a different question. The harder issue is whether the review changes how U.S. forces are positioned and protected as the Iran crisis keeps cycling between ceasefire talks and renewed attacks.

Why It Matters Now

The timing is important. The review surfaced as the United States and Iran were again trading fire around the Gulf and as Washington said technical talks with Tehran were still continuing. The crisis is not only about what happens next in the Strait of Hormuz. It is also about what the war has already cost American forces and whether those losses were preventable.

The Port of Shuaiba attack is now back in the news because the Army has finished its review and families have been briefed. Until the findings are released or described in more detail, the central question remains open: did the military simply suffer a deadly Iranian strike in wartime, or did avoidable protection failures leave U.S. troops exposed at one of the war’s most dangerous moments?
