3/ The Institute for Science and International Security ( @TheGoodISIS) reported on March 12 that the Israeli strike on the Taleghan 2 site at the Parchin military complex in Tehran Province successfully penetrated the high-explosive testing chamber at the site.

The Institute reported that the bunker buster bombs penetrated the encasing concrete sarcophagus at the suspected high-explosive test chamber hall and entered the interior of the facility. The Institute reported in January 2026 that Iran is encasing a newly-built facility at Taleghan 2 with a concrete “sarcophagus” to harden the facility against potential airstrikes.

ISW-CTP  reported on the Israeli strike on Taleghan 2 in its March 12 Morning Update and noted that the regime previously used the facility to test explosives that are needed to detonate a nuclear device before the regime suspended its nuclear weapons program in 2003. The Institute said that the Israeli strikes also damaged a few other support buildings by the main facility.

2/ The combined force struck several internal security institutions. The combined force targeted multiple IRGC Ground Forces units, which are the regime’s last resort for dealing with serious internal security threats. At least two of the strikes targeted IRGC Ground Forces sites in Khuzestan Province in southwestern Iran.

Anti-regime media and an OSINT account on X reported on March 12 that the combined force struck the IRGC Ground Forces Karbala Operational Base and 1st Hazrat-e Hojjat Independent Armored Brigade in Ahvaz. This armored brigade deployed to Syria to support the Assad regime during the Syrian Civil War.

IRGC-affiliated media reported on March 12 that the combined force struck an unspecified site in Behbahan, Khuzestan Province. The IRGC Ground Forces 15th Imam Hassan Mojtaba Special Forces Brigade operates out of Behbahan and was likely involved in suppressing protests in Izeh, Khuzestan Province, during the 2022 Mahsa Amini protests.

The combined force also targeted security forces in Tehran. An OSINT account on X stated on March 12 that the combined force struck a security checkpoint “packed with IRGC personnel” in southwestern Tehran.

Commercially available satellite imagery shows that the combined force struck the Khavar Shahr Military Garrison in Tehran.

The combined force continued to target Iranian military sites and degrade Iranian air defenses. Commercially available satellite imagery via  @vantortech from March 11 shows that the combined force struck a military garrison and air defense system in Hakimabad, Tehran. The imagery also shows that the combined force struck the IRGC Ground Forces 20th Ramezan Independent Armored Brigade, which is one of the three brigades under the IRGC Ground Forces Sarallah Headquarters.

An open-source intelligence (OSINT) account on X posted a video on March 12 showing combined force strikes on the air defense barracks in Garmdareh, Alborz Province. The combined force also struck the General Directorate of Intelligence in Qom Province on March 10, according to an Israeli analyst citing satellite imagery from March 12.

OSINT accounts on X reported on March 12 that the combined force struck the IRGC Navy Imam Ali Naval Base in Chabahar, Sistan and Baluchistan Province. The combined force previously struck the base on February 28.Institute for the Study of War (@TheStudyofWar)NEW | Evening Iran Update: Six Key Takeaways ⬇️

1. Iranian Supreme Leader Mojtaba Khamenei issued his first statement on March 12 after the Assembly of Experts selected him as the new supreme leader on March 8. Khamenei reaffirmed the regime’s commitment to Iran’s war effort in order to achieve Iran’s long-standing objectives, including the erosion and eventual expulsion of American influence from the Middle East and the destruction of the Israeli state.

2. An Iranian-linked hacker group conducted a cyberattack on a US healthcare company on March 11, which is likely part of an Iranian effort to target the US healthcare system in order to impose political pressure on the US administration. Iran has undertaken a similar effort to impose political pressure on the United States by striking oil infrastructure in the region and oil tankers in the Strait of Hormuz.

3. The US and Israeli combined force has continued to target Iranian internal security and military sites across Iran. CTP-ISW has observed strikes in ten provinces since 8:00 AM ET on March 12.

4. Anti-regime media reported that the Iranian armed forces are facing deepening fractures between the Artesh and the IRGC amid severe supply shortages, citing unspecified informed sources. Some Western media reports have indicated that there are no signs of mass defections within the Iranian armed forces or fractures within the regime yet, however.

5. Recent US Central Command (CENTCOM) operations are attempting to limit Iran’s ability to disrupt shipping in the Strait of Hormuz. CENTCOM said on March 12 that it has destroyed over 30 Iranian minelaying ships and that it has targeted naval mine warehouses and manufacturing facilities across Iran.

6. Hezbollah appears to be relying more heavily on drones to attack IDF forces and positions. Hezbollah’s reliance on drones is notable given that Hezbollah did not heavily rely on drones during the October 7 War.—  https://x.com/TheStudyofWar/status/2032299357253300396
