Russians themselves report many AGM-88 missiles being intercepted by SAMs, and I have yet to encounter proof that the AGM-88 has taken down a single SAM or radar unit during this war. Drone footage please even the Russians need to exercise drone hit confirmation as they do with the Lancets. On top of all this, MiG-29 with AGM-88 are constantly getting shot down by different means including air to air by Su-35 and MiG-31.
Ukrainians found a way to get HIMARS through Russian AD defenses by firing HIMARS with Grad MLRS for saturation attacks, with the Russian AD taking out the Grad rockets and letting the HIMARS through. This was rectified by a software update on the AD systems that help identify HIMARS tracks from Grads.
Thirdly, not just Pantsyrs but Buk M2, Buk M3 and S300V systems are involved with the interception of HIMARS and all other MLRS rockets. This does not mean however that all the gaps are plugged, given the RCS of any MLRS rocket, only short to midrange interception is possible which still means many areas remain uncovered.
For something unrelated so I don't have to post it separately, a Ukrainian Kazak 2M1 lies burning after hit by artillery.
