On February 28, 2026, the Israel Defense Forces confirmed that 40 senior Iranian military commanders were killed in simultaneous opening strikes during a joint U.S.-Israeli military operation. Among the dead: Maj.-Gen. Abdolrahim Mousavi, Iran’s Chief of Staff of the Armed Forces, along with Supreme Leader Ayatollah Ali Khamenei himself, Iran’s Minister of Defense Aziz Nasirzadeh, and dozens of other top-ranking officials. The strikes, carried out across multiple Iranian cities within approximately one minute, represent the single most devastating decapitation strike against a nation’s military leadership in modern history.
Israel codenamed the operation “Roaring Lion,” while the United States designated it “Operation Epic Fury.” Targets included sites in Tehran, Isfahan, Qom, Karaj, and Kermanshah. The IDF stated afterward that “the majority of the highest-ranking senior military officials of the Iranian security leadership have been eliminated.” Iranian forces responded within hours, launching missiles at Tel Aviv, Haifa, and U.S. military bases in the Persian Gulf. This article breaks down who was killed, what the strategic implications are, how the operation was executed, and what the Iranian retaliation looks like so far.

Who Were the 40 Senior Iranian Commanders Killed in the IDF Strikes?
The IDF has not released the full list of all 40 commanders killed, but the confirmed names read like a roster of Iran’s entire national security apparatus. Maj.-Gen. Abdolrahim Mousavi served as Chief of Staff of the Armed Forces, a position he assumed after his predecessor Mohammad Bagheri was killed in Israeli strikes in June 2025. Ali Shamkhani, the Secretary of Iran’s National Security Council and a personal security advisor to Khamenei, was also confirmed dead. Mohammad Pakpour, Commander of the IRGC ground forces, and Salah Asadi, Chief of intelligence in Iran’s military emergency headquarters, were among the others identified.
Two names stand out for their institutional significance. Mohammad Shirazi had served as Chief of Khamenei’s military bureau since 1989, making him one of the longest-serving figures in the Islamic Republic’s security establishment. Aziz Nasirzadeh, a former air force chief who had been elevated to Minister of Defense, represented the conventional military side of Iran’s dual command structure. The simultaneous elimination of figures spanning the IRGC, the regular armed forces, the intelligence apparatus, and Khamenei’s personal military office means that virtually every branch of Iranian military command was hit at once. It is worth noting that the full list of 40 remains classified or unreleased. The confirmed names account for seven of the highest-ranking officials, but the remaining 33 likely include brigadier generals, regional commanders, and senior intelligence officers whose identities may emerge in the coming days and weeks.
How Were Simultaneous Strikes on Two Sites Executed in Under One Minute?
The operational precision of the February 28 strikes is difficult to overstate. Forty senior commanders were killed across two separate sites within approximately one minute, according to the IDF’s own timeline. That kind of synchronization requires real-time intelligence on the exact locations of targets, pre-positioned strike assets capable of near-instantaneous delivery, and a level of coordination between U.S. and Israeli forces that suggests months or years of planning. The strikes hit five Iranian cities: Tehran, Isfahan, Qom, Karaj, and Kermanshah. Tehran, as the capital, housed Khamenei’s compound and likely the primary concentration of senior officials.
Isfahan and Karaj host significant nuclear and military research infrastructure, while Qom is a center of clerical and political power. Kermanshah, near the Iraqi border, has long served as a staging area for IRGC operations in the region. However, if the operation was designed purely as a decapitation strike, its effectiveness depends entirely on what comes next. History offers a cautionary comparison: the 2020 killing of IRGC Quds Force commander Qasem Soleimani was a precision strike that eliminated one man but did not fundamentally alter Iran’s proxy warfare strategy. The scale here is categorically different, but the question remains whether destroying leadership translates into destroying capability. Iran’s military infrastructure, its missile stockpiles, and its network of regional proxies were not eliminated by killing 40 commanders, and the retaliatory missile launches at Tel Aviv, Haifa, and U.S. bases within hours suggest that operational capacity survived the initial blow.
The Death of Ayatollah Khamenei and What It Means for Iran’s Government
The killing of Ayatollah Ali Khamenei in the strike on his Tehran compound is the single most consequential element of the operation. Khamenei had served as Supreme Leader since 1989, succeeding Ayatollah Ruhollah Khomeini as the highest authority in Iran’s theocratic system. His death does not merely remove a political figure; it eliminates the constitutional center of gravity in a system designed around the concept of velayat-e faqih, or guardianship of the Islamic jurist. Iran’s Assembly of Experts is constitutionally responsible for selecting a new Supreme Leader, but that body has never had to exercise this power under conditions of active military assault and near-total leadership decapitation.
The simultaneous loss of Khamenei, his personal military bureau chief Shirazi, his security advisor Shamkhani, and the Chief of Staff creates a power vacuum with no obvious precedent. For comparison, even the assassination of Egyptian President Anwar Sadat in 1981, which removed a single head of state, triggered a complicated and contested succession. The scale of leadership loss here is orders of magnitude greater. The practical question is whether Iran’s remaining clerical and political establishment can reconstitute command authority quickly enough to manage the ongoing military crisis. The IRGC has always maintained parallel command structures partly for this reason, but losing both the Supreme Leader and the IRGC ground forces commander simultaneously tests even those redundancies.
Iranian Retaliation and the Escalation Risk
Iranian forces responded to the strikes within hours, launching missiles at Tel Aviv, Haifa, and U.S. military bases in the Persian Gulf. The speed of the response suggests that retaliatory plans were pre-positioned, which is standard military doctrine for a nation that has been under escalating threat of attack. The targeting of both Israeli cities and American military installations confirms that Iran views the operation as a joint U.S.-Israeli action, not an Israeli operation with American support. The tradeoff at the center of this crisis is familiar but now carries existential stakes. For the U.S.
and Israel, the strikes represent a calculated bet that destroying Iran’s leadership will weaken its capacity to wage asymmetric warfare through proxies like Hezbollah, Hamas, and the Houthis. The potential payoff is enormous: a fundamentally weakened adversary. But the risk is equally enormous. A decapitated regime with surviving missile capability, a network of armed proxies, and nothing left to lose is arguably more dangerous in the short term than a stable adversary operating under rational deterrence. For American military personnel stationed in the Gulf, the immediate concern is the retaliatory missile strikes on U.S. bases. The scope and effectiveness of those strikes will determine whether this escalation remains a U.S.-Israeli offensive operation or becomes a broader regional war with American casualties driving further escalation.
The Intelligence Failure That Made Iran’s Leadership Vulnerable
The fact that 40 senior commanders were gathered in locations known to and targeted by the IDF raises unavoidable questions about Iranian counterintelligence. This is the second time in less than a year that Israel has successfully struck Iran’s most senior military leadership. Mohammad Bagheri, Mousavi’s predecessor as Chief of Staff, was killed in June 2025. That strike should have triggered a comprehensive overhaul of Iranian operational security protocols for senior officials. The limitation of any analysis at this stage is that we do not know the full circumstances.
It is possible that the two strike sites were considered hardened or secure facilities that Iran believed were beyond Israeli reach. It is also possible that the intelligence penetration of Iran’s security establishment runs deeper than previously understood. Israel’s intelligence services have demonstrated repeated ability to operate inside Iran, from the Mossad’s 2018 extraction of Iran’s nuclear archive to the series of assassinations targeting nuclear scientists. What is clear is that Iran’s leadership protection protocols failed catastrophically. Whether that failure was the result of complacency, intelligence penetration, or simply the overwhelming technical capability of the strike itself, the result is the same: the Islamic Republic’s senior military and political leadership was effectively wiped out in a single coordinated attack.
The U.S. Role in Operation Epic Fury
The United States designated its participation “Operation Epic Fury,” a name that makes clear this was not merely logistical support for an Israeli operation. The joint nature of the strikes, hitting targets across five Iranian cities simultaneously, almost certainly required American assets including intelligence, surveillance, reconnaissance, and potentially strike platforms. The U.S.
has maintained significant military assets in the Persian Gulf region, and the operational scope of the February 28 strikes far exceeds what Israel could likely execute unilaterally at that distance. The decision to conduct a joint operation rather than allowing Israel to act alone carries significant implications for U.S. legal authority, congressional notification requirements, and the broader question of whether the United States is now formally at war with Iran. The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action, and the scope of Operation Epic Fury would appear to trigger that obligation unambiguously.
What Comes Next in the U.S.-Iran-Israel Conflict
The February 28 strikes have created a situation with no modern precedent: a major regional power has lost its head of state, its chief of staff, its defense minister, its intelligence chief, and dozens of other senior military officials in a single day. The immediate question is whether Iran’s surviving leadership structure can maintain coherent command and control over its military forces and its network of regional proxies, or whether the country descends into internal chaos while simultaneously prosecuting a retaliatory military campaign. The longer-term question is whether this operation achieves its apparent strategic objective of permanently degrading Iran’s ability to threaten Israel and U.S.
interests in the region. The killing of Qasem Soleimani in 2020 was supposed to cripple Iran’s proxy warfare capabilities; it did not. The scale of the February 28 operation is vastly greater, but Iran’s institutional resilience, its entrenched proxy networks, and its surviving missile and drone capabilities mean that the answer will not be clear for months or years. What is clear right now is that the Middle East has entered a fundamentally new and more dangerous phase.
Conclusion
The IDF’s confirmation that 40 senior Iranian military commanders were killed in the opening strikes of a joint U.S.-Israeli operation marks a turning point in the long-running conflict between these nations. The deaths of Ayatollah Khamenei, Chief of Staff Mousavi, Defense Minister Nasirzadeh, IRGC ground forces commander Pakpour, intelligence chief Asadi, Khamenei’s military bureau chief Shirazi, and security advisor Shamkhani represent the most comprehensive elimination of a nation’s military and political leadership since World War II. The operational achievement is extraordinary; the strategic consequences remain deeply uncertain.
The Iranian retaliatory strikes on Tel Aviv, Haifa, and U.S. military bases in the Persian Gulf within hours of the attack demonstrate that military capability survived even as leadership did not. The coming days and weeks will determine whether the loss of 40 senior commanders translates into lasting strategic advantage or triggers an escalatory spiral that draws the entire region into open war. For American citizens, servicemembers, and policymakers, the stakes could not be higher.
