Sadly, they’ve just done it again.
The IRBM hit an underground gas storage facility near Lviv and during very cold weather, reduced heating gas pressure to a very low level. Unless engineers and technicians find a way to re-route gas, this can result in widespread infrastructure damage (water pipes freezing).
Russia also drone-swarmed Kyiv and knocked out half of the heating - the mayor, Vitaly Klychko, recommended that people who happen to have an alternative place of living should leave town. This will likely result in the same kind of damage.
Ukraine responded and knocked out electricity in the Belgorod oblast of Russia. It may be guessed that people in Belgorod aren’t enjoying the moment either.
War against heating infrastructure in winter is war against civilians.
Fortunately, this type of IRBM is scarce, Russia currently produces 2…3 of them per year (it’s a new product, no stockpiles), so it can be used for signaling and high priority strikes, but not constant bombardment.
Ah, an Intermediate-Range Ballistic Missile missile.
