Honestly, this isn't Kursk, or a battle of Hannibal. The technology is just too different.
This is Bakhmut. This will end like Bakhmut.
Drones are changing things. They can menace tanks and absolutely devastate infantry. Also the best spotters for artillery.
This may change in the future with drone hunter drones or flak vehicles that can detect them in the future.
The drones also help the more artillery force, Da OrkZ, in this one.
Maybe it costs the Russians, but they haven't even fully mobilised yet, and got greater reserves ready to deploy.
I also don't think the US support will be in any danger unless Israel is totally cornered and China finally gets off the toilet and shits on Taiwan.
Z man's death would just damage coke stonks. If he was that big a threat, the Kommandorks would have slipped something in his tea already.
It isn't a video game or isekai where you kill the leader and their state instantly goes belly up.
