United Kingdom's Ministry of Defense shared on Tuesday in its most recent intelligence report that Russia has been recalibrating its "short and medium-range air defenses," in recent weeks, trying to protect itself "more effectively" from Ukraine's drone attacks.
"Since early September 2023, Russian SA-22 air defense systems around the capital have been pictured positioned on elevated towers and ramps. Previously, following strikes against Engels and Ryazan air bases in December 2022, Russia also positioned SA-22 on the roofs of official buildings in Moscow," the ministry said.
It explained that such moves were "almost certainly" taken in order to enable the systems to detect and engage drone-type targets. In addition, the ministry believes that this reassures the public that everything is "under control."
