There is lots of misinformation online, but what I've been able to glean is that the area is under heavy attack, Ukrainians are being pushed back while inflicting heavy casualties on the RU forces (for weeks/months now) but are nearly to a point retreat must be considered.
Artillery ammo shortages are a significant factor for the UA defense.
For the RU side, it's been meat wave after wave. Not the town is that critical strategically, but this is politics of the Wagner group showing they can be effective vs the disaster of a fall campaign for the R army.
For the West, were are fooling ourselves if we think the Russian army isn't dangerous and destined to lose. As many conflicts in the past, they will make absurd demands, make insane and bloody sacrifices, but still hold out for measures of concessions they know the soft West will give. That's the reward and incentive they expect, and will get them to fight the next war.
We have to do more quicker. Hasn't changed since Feb 2022. New weapons are good, but also ammo production will be a major factor.
