There is increasing demand among frontline troops for the robots, which move on wheels or tracks and are controlled by radio signals like aerial drones. They can range in size from smaller than a microwave to large enough to carry multiple people. The number of tasks the robots completed across the front line nearly doubled from August to September, according to Ukraine’s top commander. Ukrainian soldiers hope the robots can take over more basic frontline tasks, sparing troops from some of the more dangerous work of the ground war.

This is completely wrong, the tanks were used in the big spring offensive 2023 that unfortunately failed, and was way to costly compared to what was gained. Which is why we never heard much about it after the fact. But the superiority of the German Leopard and the American Abrams tanks over Russian tanks, was exactly one of the factors that was supposed to help Ukraine.

It was absolutely not Ukraine that failed to seize the opportunity, but the west that failed to deliver as promised. So mechanized brigades that were trained for and supposed to have modern western tanks were only equipped with obsolete T64 tanks!
