Iran is rebuilding the upper ranks of its military and security establishment after months of wartime losses by turning largely to familiar veterans — figures whose careers in some cases stretch back to the 1979 Islamic Revolution, the Iran-Iraq War and previous domestic crackdowns.

The appointments follow the deaths of several senior Iranian commanders in U.S.-Israeli strikes since the war began Feb. 28, national-security policy and internal security at a time of renewed confrontation with the United States.

The appointments do not prove that Tehran has run out of younger commanders or that loyalty was the sole criterion, but the reliance on figures whose careers stretch back decades is raising a broader question for U.S. policymakers: whether wartime losses have left Iran increasingly dependent on a smaller circle of trusted ideologues — potentially narrowing the room for compromise even as Washington tries to pressure Tehran back toward a deal.

Former American prisoner Morad Tahbaz, who was detained in Iran in 2018 and freed in a U.S.-Iran prisoner exchange in September 2023, told Fox News Digital that he views the latest appointments as evidence of Tehran's continued dependence on longtime loyalists.

"They keep rotating the same old people, most of whom are fairly inept but are loyal to the Khamenei father and son," Tahbaz told Fox News Digital.

The reshuffle spans Iran's conventional military, the Islamic Revolutionary Guard Corps, its naval arm, the Basij paramilitary force and the country's highest national-security council.

One of the most closely watched appointments is Hossein Taeb, the cleric and veteran security official tapped to lead the Basij, the IRGC's volunteer paramilitary force that has repeatedly been used against domestic dissent.

The National reported that the Basij has been used to suppress internal dissent, whileMiddle East Forum that Heydari's previous public rhetoric surrounding protest suppression indicates that Tehran has increasingly integrated the regular army into its domestic-security posture.

Mostafa Izadi: Another veteran rises inside the IRGC

Mostafa Izadi was appointed Vahidi's deputy, putting another longtime commander near the top of the IRGC hierarchy.

IRNA confirmed Izadi's appointment Aug. 10, while The National described him Aug. 11 as a veteran commander who has held a number of senior positions in Iran's military and security establishment.

Iran International reported that Izadi previously commanded the Cyber and New Threats Headquarters within the Khatam al-Anbiya Central Headquarters.

Rear Adm. Ali Ozmaei was appointed commander of the IRGC Navy, putting him in charge of a force central to Iran's military posture in the Persian Gulf and Strait of Hormuz.

The National reported Aug. 11 that Ozmaei replaced Alireza Tangsiri, who was killed in an Israeli airstrike in March, and that the IRGC Navy is responsible for Iran's military operations in the Gulf and around the Strait of Hormuz.

Iranian state media also highlighted Ozmaei's longstanding maritime experience. IRNA reported Aug. 11 that Parliament Speaker Mohammad Bagher Ghalibaf praised Ozmaei's years in maritime defense and his familiarity with the current conflict and the Strait of Hormuz. 

The appointment came one day before Rezaei said the Strait of Hormuz would remain closed unless the United States changed its behavior and accepted Iran's conditions. Reuters reported that Rezaei said Washington would have to end the war and unfreeze Iranian funds overseas, with other conditions relayed through mediators.

Taken together, the seven personnel changes show Tehran moving to fill and reshuffle critical military and security posts after significant wartime losses. What remains an assessment rather than an established fact is whether the identities of those chosen reveal a deeper shortage of trusted successors.

Sabti said the return of veteran figures reflected what he sees as a shrinking bench of trusted officials and a less diverse decision-making circle.

Tahbaz offered a less academic version of that assessment.

"They keep rotating the same old people," he said.
