I didn't see this posted yet and is perhaps the most culturally important gaming development that has occurred ever.
Without getting into politics or morality of sides, war has been forever changed and favors cheap rapid drone deployment overwhelming more expensive weapons and soldiers. Now the neckbeard eating Cheetos can kill 10 elite soldiers before lunch when he drinks a mountain dew.
Ukraine has released a drone training simulator, and is allegedly similar to how they train their people. They have managed against all odds to repel a much larger and better equipped foe, and are even exporting their tactics and training to the middle east.
These sorts of tactics put heavy manufacturing countries like China in an advantaged spot that I think other countries now must adapt to.
I'd say in terms of experience thanks to the corruption I mentioned before, Russia isn't going to benefit as much after this as they've been TOO MUCH using meat grinder tactics, including with talented soldiers because they could bribe as much.
But Ukraine's ALREADY getting money from their experienced drone operators and developers. It would be funny if this ends up another UNIT 731 situation where all their corruption is forgiven for their technical knowledge.
