Russian infantry slipped past Ukrainian defenses around the city of Kupiansk, in Kharkiv Oblast, on or before Tuesday. A Ukrainian tank, presumably from the 116th Mechanized Brigade, rolled right up to the half-demolished building the Russians were sheltering in—and blasted them at point-blank range.
It’s the latest instance of Ukrainian tanks engaging, and defeating, under-supported Russian infantry in a close fight. But it’s an ominous development for Ukraine. The brutal, zero-distance skirmish took place in Kupiansk, a town with a pre-war population of 25,000 and a key strongpoint anchoring Ukrainian defenses just 90 km east of Kharkiv and its millions of residents.
Russian infantry weren’t supposed to appear inside Kupiansk, some 6 km from what most mappers consider the “front line” in Kharkiv.
The problem, of course, is that the front isn’t really a line anymore. “The reality is that there isn’t a coherent front line,” American analyst Andrew Perpetua explained.


Positive view: this is Ukraine rope-a-doping Russia into sending soldiers far enough ahead that they aren’t protected by drones and therefore can be eliminated with few or zero Ukrainian casualties.
Negative view: Ukraine doesn’t have enough infantry and so Russia will start to push the Ukrainians back more and more
