Edited part of the map of this dude: >>51698 so the strongholds can be seen better. Clément drew the fortifications in blue, and used blue to shade Ukraine held territory. So it's a bit hard to see.
It's the Avdiivka front (Tsentr Group) towards Pokrovsk. There is one chain of trenches from Stara Mykolaivka in the north through Ocheretyne and Komyshivka to Vovchenka in the south where the line can settle. They might just push in the center to about Novoselivka Persha which Russians could take. And they gonna have a bulge there.
I think a lot will depend on Krasnohorivka.
