Iran’s Revolutionary Guards Restructured Hezbollah After 2024 Defeats

Iran's Revolutionary Guards deployed about 100 officers to Lebanon to rebuild Hezbollah's military command structure following devastating losses to Israel in 2024. The reorganization replaced hierarchical leadership with decentralized cells to prevent future intelligence breaches that had enabled Israel to eliminate top commanders.

Iran’s Revolutionary Guards completely restructured Hezbollah’s military operations following the Lebanese group’s devastating losses to Israeli forces in 2024, according to sources with knowledge of the Iranian activities.

The unprecedented reorganization by the IRGC came after Israel decimated Hezbollah’s leadership structure, including the assassination of longtime leader Hassan Nasrallah and numerous senior commanders throughout 2024.

Two sources familiar with the Iranian operations revealed that the Revolutionary Guards deployed officers to fill command gaps and completely overhaul the Shi’ite organization that Iran originally established in 1982.

This marked the first comprehensive restructuring in Hezbollah’s history, demonstrating Iran’s direct intervention following the severe damage inflicted during the previous conflict.

The Iranian investment appears to have succeeded in restoring Hezbollah’s capabilities in time for the current Middle East conflict, where the group has joined the fighting alongside Tehran after attacks by the United States and Israel.

According to the sources, IRGC personnel arrived in Lebanon to retrain fighters and supervise weapons replenishment efforts. The Iranian officers also redesigned command systems that Israeli intelligence had successfully penetrated, which had enabled the targeted killings of multiple Hezbollah leaders.

An Israeli military representative acknowledged on March 12 that despite three years of Israeli operations against it, Hezbollah continues to pose a significant threat.

Since joining the regional conflict on March 2, Hezbollah has launched hundreds of rockets toward Israel, triggering Israeli counterattacks that have resulted in over 1,000 Lebanese casualties. Ground fighting continues as Hezbollah militants engage Israeli forces occupying southern Lebanese territory.

However, questions remain about Hezbollah’s performance capabilities, as its strength has not yet returned to previous peak levels, particularly if facing a comprehensive Israeli ground invasion.

Israeli Prime Minister Benjamin Netanyahu stated in January that Hezbollah was actively working to rearm and reconstruct its infrastructure with Iranian assistance.

The IRGC officers assigned to assist Hezbollah’s recovery arrived shortly after the November 2024 ceasefire took effect, continuing their work despite ongoing Israeli airstrikes. One source indicated approximately 100 officers participated in the deployment.

The restructuring eliminated traditional hierarchical command in favor of a decentralized network composed of small, independent units with limited knowledge of other operations, enhancing security and operational secrecy.

Iranian officers also developed coordinated missile attack strategies targeting Israel that would be executed simultaneously from both Iran and Lebanon – a plan first implemented on March 11.

A senior Lebanese security official confirmed that Iranian commanders assisted Hezbollah in rehabilitating and reorganizing its military personnel. The official believes the Iranians are helping manage the pace of current hostilities rather than selecting specific targets.

Another informed source said the IRGC deployed officers to Lebanon in 2024 to conduct a comprehensive post-conflict assessment of Hezbollah and assumed direct oversight of its military operations.

Two additional sources confirmed that the IRGC embedded specialized advisers with Hezbollah throughout the previous year to guide military decision-making.

Andreas Krieg, a lecturer in security studies at King’s College London, explained that the IRGC “has basically reorganized Hezbollah as a far more flat system,” contrasting this with the political hierarchy that had developed around Nasrallah before his death.

“That decentralized model that they’ve now implemented is also a bit more like what Hezbollah looked like in the 1980s – very small cells,” said Krieg, who has studied the organization for 15 years. He characterized this as a “mosaic defence” strategy also employed by the IRGC within Iran.

The Iranian restructuring efforts proceeded simultaneously with attempts by Lebanon’s government and its U.S.-supported military to advance disarmament of the group, highlighting significant obstacles to achieving that goal.

Lebanon estimates approximately 100 to 150 Iranian nationals in the country maintain government connections extending beyond standard diplomatic roles, including IRGC affiliations, according to a Lebanese official.

The official said the government requested these individuals leave Lebanon in early March.

The sources familiar with IRGC activities confirmed that Guards officers were among more than 150 Iranians who departed Beirut on a March 7 flight to Russia.

IRGC personnel were among roughly 500 people killed in Israeli attacks on Lebanon during the 15 months between the 2024 ceasefire and the outbreak of renewed fighting. Approximately twelve additional IRGC members have died in Israeli strikes since the current war began, including casualties from a March 8 attack on a Beirut hotel.

The Revolutionary Guards have maintained close involvement with Hezbollah since establishing the group in Lebanon’s eastern Bekaa Valley to spread Iran’s 1979 Islamic Revolution and combat Israeli forces that invaded Lebanon in 1982.

Qassem Soleimani, the senior IRGC commander killed in a 2020 U.S. drone strike, had collaborated with Nasrallah during Hezbollah’s 2006 conflict with Israel. When Israeli airstrikes killed Nasrallah in a bunker in Beirut’s southern suburbs, an Iranian general died alongside him.
