The cheap ass drones have made the tanks less relevant. Tanks are still OK, they work very well against snipers in the city but in open terrain they are easy targets for drones. And Russia these days employs a different strategy. It employs small squads of storm troopers, sometimes on light vehicles or motorcycles. It scouts for drone operators, and annihilates the latter with short range missiles like Iskander, or rocker artillery. Glide bombs, rocket artillery guided by drones is the name of the game.
The era of mechanized assaults has ended. And the real question is how long can Ukraine sustain this? Is Ukraine actually winning?
