Yesterday, for the first time, debris was found of a modified "9M723-2F3" Iskander-M ballistic missile in Kyiv.

This modified missile is equipped with an improved high-explosive and armour-piercing warhead, designed to destroy fortified and underground structures. It is able to deploy decoy radar targets during its terminal phase to decrease its chance of being shot down. Nevertheless, 2 of these missiles were shot down by Patriot systems on September 29. I initially confused them as Oniks missiles, likely due to these radar decoys being deployed.

It's currently unclear if this is the same missile as the well-reported "Iskander-1000" missile, which is an Iskander-M with an extended range of 1000 km (the stated range of ordinary Iskander-Ms is 500 km).

It's likely that Russia intends to use this missile to destroy fortifications constructed around energy infrastructure objects and other critical infrastructure, alongside the new Geran-4 jet-drones equipped with similar cumulative-cutting specialized warheads, which were first used on a transmission tower in Kyiv today.
