Recent deadly attacks by Iran on US forces in the Middle East underscore escalating risks for American troops and allies, even as President Donald Trump reportedly remains hesitant to commit ground forces. The past week has seen the deadliest day for US forces since an April ceasefire, with two service members killed in a missile strike on a base in Jordan on Friday, followed by a third death in Iraq on Saturday during the detonation of an Iranian drone.
These incidents, part of a broader conflict that began in February with "Operation Epic Fury," have resulted in at least 17 US service member deaths. In response, the US has conducted retaliatory strikes, including targeting a missile base in Tabriz, Iran, believed to be the origin of the attack on Jordan. Iran has also launched missiles and drones at targets in Bahrain, Kuwait, and Qatar, most of which were intercepted, and attacked commercial ships in the Strait of Hormuz, disrupting maritime traffic.
While Iran's ability to disrupt the Strait of Hormuz has been a significant development, its capacity to target land-based assets across the region, including energy infrastructure and US military bases with missiles and drones, is increasingly apparent. These capabilities suggest that the risks to US forces and allies may intensify the longer the conflict persists, regardless of the absence of a US ground invasion.
Shifting US Military Deployments and Vulnerabilities
In the initial stages of the conflict, the US military repositioned troops and equipment from Persian Gulf nations to bases in Jordan and Israel, seeking fewer local restrictions and greater distance from Iranian missile launchers. However, satellite imagery and subsequent reporting indicate that Iranian strikes inflicted more damage on these bases during the early phase than was publicly disclosed. While more distant bases might be less susceptible to direct hits, they remain within range of Iran's missile and drone capabilities. Some analysts suggest this strategic shift may have created new vulnerabilities by concentrating US personnel and equipment into fewer locations.
The recent attacks in Jordan, which has seen multiple Iranian strikes in a short period, may indicate that these targets are less defended than bases in Israel, or that Iran perceives less escalation risk by targeting Jordan. US officials have indicated to The Wall Street Journal that Iran is adapting its tactics to counter US air defenses by employing missiles that travel at high speeds and can maneuver, making interception more difficult. There is also speculation that Iran may be receiving targeting assistance from China or Russia.
Iran's Evolving Capabilities and US Air Defense Strain
Experts note that Iran's continued ability to launch sustained missile and drone attacks suggests it is in a stronger position than initially assumed. Nicole Grajewski, an expert on Iran's missile program, stated that Iran retains significant missile and drone capabilities and may have been able to reconstruct its arsenal due to the absence of constant aerial bombardment. Assessments reported in June indicated that Iran still had access to most of its missile sites and approximately 70 percent of its pre-war stockpile.
Concurrently, questions are arising about the depletion of US air defense capabilities. By the time of the April ceasefire, the Center for Strategic and International Studies estimated that the US had expended over 1,000 Patriot interceptors and between 50-80 percent of its THAAD interceptors. The Pentagon is working to accelerate the production of advanced interceptors, but this process will take time. In the interim, a scarcity of missile defense munitions could exacerbate stress on US forces if the conflict escalates. "We do not have enough [munitions] to safely sustain operations, and I don’t think the White House is aware of that," one US official told The Washington Post.
Shifting Air Superiority Landscape
The proliferation of low-cost drones, such as Iran's Shahed models, has altered the strategic landscape, enabling adversaries to target US bases at a lower cost. The combined missile and drone barrage used in the recent attack that killed two service members was designed to overwhelm defenses. While interception is the best-case scenario, it depletes valuable air defense resources. The attack on a US base in Jordan in early 2024, which killed three service members, served as a precursor to the risks US troops face when targeted by Iran's full capabilities.
Historically, the US military has operated with a high degree of air superiority since at least the Korean War. However, as far back as 2022, Gen. Frank McKenzie, commander of US forces in the Middle East, warned that air superiority is no longer a constant due to the spread of drones. These drones are compared to improvised explosive devices that previously caused significant US casualties during the Iraq War. Despite the recent fatalities, US casualties in the current conflict remain lower than those in the Iraq wars. President Trump has stated his concern over the deaths, framing the mission as preventing Iran from acquiring nuclear weapons, though recent focus has been on the Strait of Hormuz.
The current trajectory suggests that American casualties alone may not deter further military action, and retaliatory strikes, such as the one on Tabriz, could draw the US deeper into the conflict. As long as a ground invasion is avoided, Iran's ability to inflict casualties on US troops remains limited, but the events of the past weekend demonstrate that this capability exists. The longer the conflict continues, the greater the risk of more significant catastrophes for American troops in the Middle East.
