Ukrainian military officer names the Russian army's most terrifying weapon
A Ukrainian military officer in an interview with Business Insider called tanks the “most terrifying” weapon of the Russian Armed Forces on the battlefield.
According to this officer, when the Russian tanks started firing, you couldn't even hear it, you could hear the sound of planes flying overhead, not the sound of tanks.

In addition, the Ukrainian military complained about the lack of ammunition, noting that the Russian Armed Forces have access to a wide variety of weapons.
Business Insider also wrote that the Ukrainian Armed Forces can no longer rely on US-supplied HIMARS missiles or Excalibur artillery shells, as Russian electronic warfare systems are much more effective.
