Drone-Led Ukrainian Offensive Retakes Ground in Critical Eastern Front Sector

Kyiv Post | Stefan Korshak

The Ukrainian 3rd Army Corps has launched a patient, drone-led counteroffensive north of Lyman, advancing up to 15 kilometres and threatening to encircle hundreds of Russian troops. This tactical breakthrough near Drobysheve has severed a critical Russian supply route, carving a deep salient into Kremlin defences. Operating in the densely wooded and swampy terrain between the Siverskyi Donets and Zherebets rivers, Kyiv's forces have utilised a systematic approach where unmanned aerial vehicles precede and cover small infantry units.

These tactics have successfully neutralised Russian artillery and logistics, including Giatsint-B guns and Grad rocket launchers, while keeping Ukrainian casualties low. According to the Institute for the Study of War, the advance has reached the outskirts of Zarichne, raising the prospect of a larger encirclement. This operational success directly undermines Moscow's long-term strategic ambitions to capture the key Donetsk strongholds of Kramatorsk and Sloviansk.

Comment

The integration of first-person view (FPV) and bomber drones as primary organic fire support for the Ukrainian 3rd Army Corps represents a fundamental shift in assault doctrine. Rather than relying on traditional heavy artillery barrages to suppress defensive lines, these unmanned systems systematically strip away Russian field fortifications and mobile assets like the 2A36 Giatsint-B gun before infantry deployment. This continuous aerial suppression allows light infantry units to advance through difficult terrain, such as the swampy sectors near the Zherebets River, with reduced exposure to defensive fires.

This tactical sequence relies on tight coordination between decentralised drone pilots and dismounted assault teams, bypassing the traditional, centralised fire-direction centres that often delay response times. Consequently, the rapid target-acquisition loop enables the 3rd Army Corps to isolate Russian defensive pockets near Drobysheve before the 25th Combined Arms Army can coordinate effective counter-battery fire.

Strategic Question for Discussion

If the decentralised drone-led assault doctrine demonstrated by the 3rd Army Corps near Drobysheve is scaled across other sectors, does it render traditional Russian heavy artillery systems like the 2A36 Giatsint-B obsolete, or does it merely shift the bottleneck to drone manufacturing and electronic warfare capabilities?
