Heavy losses for Russia: tank fleet is easy prey for Ukraine. Jammers are supposed to protect Russia's tanks from drone attacks.

But the technology works poorly - which is why losses are increasing. According to British intelligence estimates, Putin's fleet has lost up to 2,600 tanks since the start of the Ukraine war. Video that recently appeared on Twitter shows how effective the drone attacks are. After the tank, which has no road to leave, the crew has to flee on a snowy field.
