IRGC Launches True Promise 4 Waves 83-84, Strikes US and Israeli Military Sites Across Region

The IRGC carried out Waves 83 and 84 of Operation True Promise 4 on March 27, targeting US and Israeli military assets across the Gulf and the Levant. Wave 83 struck storage tanks and the oil depot at Ashdod, a military site in Modi'in, and a US military information exchange center. Wave 84 targeted US refueling aircraft at Al-Kharj Base in Saudi Arabia. The IRGC also struck Al-Dhafra and Al-Udeiri bases and maintenance hangars at Ali Al-Salem Air Base. Iran claims all objectives achieved; independent damage assessment is unavailable.

Analysis
Wave counts have accelerated from the 27th wave on March 8 to Waves 83-84 on March 27, roughly 2.8 waves per day. The targeting of Al-Kharj Base refueling aircraft is tactically significant: degrading aerial refueling capacity constrains coalition sortie generation over Iran. Iran's daily attack tempo of ~33 ballistic missiles and ~94 drones is straining the interceptor stocks covered elsewhere in this digest.
