repelled a determined Russian attempt to breach its defensive lines in the Vovchansk area, inflicting heavy casualties on Putin's army.
Fierce fighting continues to rage on the frontlines, despite the beginning of peace talks last week between US and Russian officials.
Intense battles have erupted on the Kharkiv front in recent days, as generals attempt to capture Kupyansk and exert pressure on the city of Vovchansk.
Russian commanders launched a series of assaults, throwing infantry and armoured columns at Ukrainian positions.
However, Russian armoured vehicles soon got bogged down in a minefield, and provided easy targets for drone operators from Ukraine's 71st Jaeger Brigade.
A video clip published by the unit shows the resulting carnage as FPV drones decimated the Russian armour in a brutal aerial attack.
Images show the lead tank hitting a mine, losing one of its tracks and becoming immobilised.
Two armoured personnel carriers behind attempt to go around it but, as they manoeuvre, they are hit by drones in a lethal attack.
In a post to their Facebook page, the unit wrote: "FPV drone pilots of the 71st Jaeger Brigade everyday turn enemy equipment into scrap metal, and occupiers into the dust of history.
"They thought they could come to our land with impunity. But we are here to remind them: we did not start this war, but we will end it."
Russian commanders are trying to wear down and exhaust the Ukrainians with constant small group assaults, as they leverage their superiority in manpower and weapons.
The kamikaze attacks have resulted in high Russian casualties and a staggering loss of military equipment.
Latest figures from Ukraine's army claim that the Russians sustained another 1050 casualties over the past 24 hours.
According to Kyiv, Russia has now lost just over 868,000 thousand troops - either killed or injured - since the full-scale invasion was launched three years ago.
Data on casualties vary widely, with it almost impossible to verify data given out by either side.
have carried out their own surveys, and estimate over 95,000 of the Kremlin's soldiers have been killed since 2022.
This does not include dead soldiers from pro-Russian militias in the self-proclaimed Donbas republics - the BBC estimates that between 21,000 and 23,500 have been killed from these units.
