British analyst Alexander Merkouris stated this on his YouTube blog. 

“The glide bombs that Russian aircraft drop on the Ukrainian Armed Forces pose a mortal threat, no matter how hard the Ukrainian military tries to dig in,” he said.

According to the expert, the new fortifications of Kyiv in the Donbass and Kharkov region cannot withstand the impact of one and a half ton shells. 

Earlier, Merkouris said that after the air defense of the Ukrainian Armed Forces is depleted, Russia will begin massive missile and UAV attacks.

He also noted that Russia is destroying French CAESAR installations in Ukraine.
