Beginning to see more footage of groups of Russian vehicles being destroyed by drones. Another technology which replaces old, ground-based ones.
I hope the Ukrainians end up with hundreds and hundreds of them, hovering over every Russian column.
On another note, what a thing it would be if Putin has an unfortunate accident. Get a better Russia, remove the leader of Belarus and China will have to become more cooperative. A far better world appears. And Ukraine's name will live in glory forever, like the Greeks at Marathon.
