Well, it’s finally happened. Ukrainian lines have seen possibly their first major breach down to the operational depth, or nearly so, as Russian forces struck out as much as 20km north of Pokrovsk. But the real story is much more nuanced than that.
Russian troops had been accumulating there in small pockets since late July, shaping the ground. A fierce debate has erupted over whether these are “DRGs” or regulars as Ukrainian accounts have lazily resorted to labeling anything penetrating the first line of defense as “DRGs”, but in reality these are mostly regular troops which simply accumulated in a weakened portion of the front. Hotspots on the front, where main assaults are expected, act as a kind of gravitational force, pulling everything toward them, and sucking resources and reinforcements in the sector away from neighboring lower-priority fronts.
You can see below, the yellow lines represent active Russian advancing operations, and the blue lines represent Ukrainian resources being pulled to plug the gaps and staunch the flow. But these resources are pulled away from a de-prioritized area which then “bursts” forward (red line), provided that Russian intelligence is aware enough of Ukrainian operational deficits there:
