Israel Kills Iran’s Basij Commander as Leadership Decapitation Accelerates
Gholamreza Soleimani's death marks the second-highest-level assassination in the 17-day US-Israel campaign, exposing vulnerabilities in Iran's domestic security apparatus.
Israeli forces killed Gholamreza Soleimani, commander of Iran’s 450,000-strong Basij paramilitary force, in a targeted airstrike in central Tehran on 16 March, eliminating the majority of the organization’s senior leadership in a single strike.
The assassination—confirmed by the IRGC via the Tasnim news agency on 17 March—represents the second-highest-level targeted killing in the 17-day US-Israel Military campaign against Iran, following Supreme Leader Ayatollah Ali Khamenei’s death in the opening strikes on 28 February. An Israeli official told the Jerusalem Post that the strike eliminated the majority of Basij leadership overnight, dealing a severe blow to the force responsible for suppressing internal dissent and enforcing ideological conformity across Iran’s 31 provinces.
Command Structure Under Pressure
Soleimani had led the Basij since July 2019, overseeing the force’s transformation into the regime’s primary instrument for domestic control. In January 2026, the Basij deployed heavily to crush antigovernment demonstrations across Iran, operations during which thousands of Iranians were reportedly killed, according to Al Jazeera. His death removes the architect of that suppression apparatus at a moment when the regime faces potential unrest following the supreme leader’s assassination.
The Israeli Defense Forces stated the strike was “guided by precise intelligence from Military Intelligence” and conducted “in the heart of Tehran,” demonstrating continued operational reach into Iran’s capital despite 17 days of sustained combat. Israeli Defence Minister Israel Katz framed the killing as part of a broader decapitation campaign: “The leaders of the regime are being killed and their capabilities terminated.”
“These units are operating based on general instructions given to them in advance, rather than direct, real-time command from the current political leadership.”

Decentralized Command Meets Internal Security Crisis
Iran has responded to the leadership losses by implementing what Foreign Minister Abbas Araqchi described as a decentralized command structure, with 31 autonomous provincial IRGC units operating on pre-positioned general instructions rather than real-time central command. The system—dubbed ‘Mosaic Defence’ by Radio Free Europe—empowers local commanders to act independently, reducing vulnerability to further leadership strikes.
But the decentralization strategy was designed for external military operations, not internal security. The Basij’s primary function is domestic control—maintaining ideological conformity, mobilizing regime supporters, and suppressing dissent. Its integration into the IRGC command structure means provincial Basij units now operate under the same decentralized framework, but without the senior leadership that coordinated nationwide responses to unrest.
The Basij was established in 1979 as a volunteer militia and formally integrated into the Islamic Revolutionary Guard Corps in 2007. Estimates of its membership range from 450,000 active personnel (Institute for the Study of War) to nominal rolls exceeding 10 million. The force operates through a cellular structure embedded in mosques, universities, and workplaces, serving as the regime’s eyes and ears across Iranian society.
Proxy Coordination Shows Mixed Results
Iran’s regional proxy network has delivered an uneven response to the conflict. Hezbollah launched rocket attacks against Israel within two days of the 28 February strikes, demonstrating maintained coordination capacity. Iraqi militias have similarly entered the conflict. But the Houthis—previously Tehran’s most active proxy force—have conducted no operations outside Yemen since October 2025, according to ACLED data.
The Houthi restraint may reflect uncertainty about Iran’s ability to provide strategic direction or resupply under sustained military pressure. The Stimson Center notes that proxy burden-sharing in the current war depends on each group’s assessment of whether Iran can sustain the broader Axis of Resistance architecture—a calculation complicated by the deaths of both supreme leader Khamenei and key IRGC commanders who managed proxy relationships.
Succession Planning Meets Reality
Iran’s stated succession planning includes three-rank replacement nominees for senior positions, designed to ensure command continuity. But the simultaneous elimination of multiple tiers of Basij leadership in a single strike tests whether these plans can function under rapid, concentrated attacks. The new Supreme Leader, Mojtaba Khamenei, has made limited public appearances since his father’s death, raising questions about whether he can assert authority over provincial commanders now operating with pre-positioned instructions rather than central direction.
Mohamad Elmasry, a professor at the Doha Institute for Graduate Studies, told Al Jazeera that leadership losses alone won’t collapse the regime: “There’s always another leader … so I don’t think this is going to suggest any kind of collapse of the Iranian regime.” But the comment assumes replacement leaders inherit functioning command structures—an assumption undermined when entire organizational hierarchies are eliminated overnight.
What to Watch
The real test of Iran’s decentralized command structure will come if domestic unrest emerges in the coming weeks. Provincial Basij units must coordinate suppression responses without the senior leadership that orchestrated the January 2026 crackdown. Watch for signs of uneven or delayed responses to protests across different regions—an indicator that decentralization has created coordination gaps rather than resilience.
On the external front, monitor whether Houthi restraint continues or whether pressure from Tehran’s remaining leadership pushes the group into the conflict. Israeli Prime Minister Benjamin Netanyahu framed the campaign as giving Iranians “the opportunity to take their destiny into their own hands,” per NBC News—a signal that Israeli strategy pairs military decapitation with expectations of internal instability. The elimination of the force responsible for preventing that instability may indicate a calculated bet that Iran’s mosaic defense can survive external pressure but not the combination of external strikes and internal collapse.
