Give Ukraine lots of long-range missiles. As many as they want. Atacms, Himars, Storm Shadow, Taurus - you name it.
Make it so that the frontline + anything within a 1000km range is a potential target. Every singly supply depot, every ammo cache, every freight train moving weapons to the frontline has the potential to be blown to pieces.

This way all ~600k remaining ziggers on the front are sitting ducks. Within days they will be starving and be vulnerable to being hit with zero reinforcements on the way.
