I would be concerned about anti-tank weapons operated by both foot-soldier and drone. Much of this war seems to be trench warfare making difficult targets.
If the US was fighting this war, they would first gain air superiority, then send in the A10’s to kill the tanks and artillery. That would be a game changer. But since the Ukraine doesnt have a chance in the air, its all about a ground war where they are vulnerable from inferior artillery numbers, drones and soon, manpower. I think Musk had the best solution for a peace settlement.
