Britain's defense ministry said Russian forces likely only have a few key systems remaining.
For ground troops to surmount these obstacles means navigating through a slow and deadly process, and Ukrainian forces lack air superiority.
"Russian ground forces survivability relies on effectively detecting Ukrainian artillery and striking against it, often with its force's own artillery," Britain's defense ministry said in a Monday intelligence update.
According to an analysis by the open-source intelligence site Oryx, at least 38 Russian radars have been destroyed, damaged, or captured in Ukraine.
"The priority Popov apparently gave to this problem highlights the continued centrality of artillery in the war," Britain's defense ministry said.
