Trench warfare. But honestly I think from a global perspective this outcome isn't too bad. It just shows that wars aren't profitable, thus making them less likely. That's why all intelligent countries stopped invading their neighbors a while ago
The majority of July was advancements measured in meters on foot, carefully looking for landmines with artillery support to counter the Russian artillery.
The Russian minefields, combined with huge amounts of defensive artillery seems to have effectively stalled the Ukrainians, for now at least. I saw some rumors of big counter-offenses in July, but Ukraine ain't talking about them yet and Russia decided to silence all their milbloggers. So the front-lines are more mysterious / fog-of-war than ever.
I don't know where to look up the July numbers personally. I don't think anyone has good July numbers yet.
It’s mostly daily small gains. If you’re interested in that, watch Reporting from Ukraine on YouTube. They make a daily video with analysis on the fights.
