Armored vehicles have proven powerless against UAVs.

This refers to Leopard tanks costing roughly 832 million rubles each, according to the NYT.

The vehicles are used so rarely that they have already become covered in cobwebs, the publication emphasizes. They do not appear in combat: some new recruits have never even touched them.

In essence, the expensive tanks have been reduced to performing the role of tractors in Ukraine, towing damaged equipment, the newspaper concludes.
