Extraordinary new footage shows the moment that a Ukrainian first-person view (FPV) drone uses a built-in shotgun to destroy three incoming Russian aerial threats before turning fire on an enemy soldier.

The video shows the Kyiv drone shooting down three Russian drones - identified as Chinese-made Mavics - which may have been on reconnaissance missions.

Soon after, the FPV drone shoots at - and hits - a Russian “invader” before “finish[ing] him off” by dropping a grenade, reports add.

The footage was taken over Synkivka and Petropavlivka, villages in Kharkiv district of Ukraine.

The video highlights the fearsome war capability of the latest military drones piloted by remote controllers. While the type of the Ukrainian drone has not been revealed, it clearly demonstrated its warfare potential.

This is the first time such a drone is seen being used against an enemy infantryman.

"The Ukrainian drone shoots down three Russian Mavics with a shotgun, then shoots at the invader with the same shotgun and finishes him off with a grenade,” said Ukrainian military journalist Andriy Tsaplienko.

Last month, footage emerged of a Ukrainian-made Winchester drone using buckshot to shoot down approaching Russian aerial threats.

“Drones armed with shotguns have proven remarkably effective in combating enemy drones, including those operating via fibre optics,” reported Focus Ukraine.

“Winchester drones can shoot down other drones mid-flight using buckshot. The development is already being used by Ukrainian defenders,” the report added.

Buckshot is a collection of many small metal balls fired from a shotgun.

Ukraine has also pioneered missile-firing FPV marine drones, which have taken down several military helicopters.

Such sea drones are also capable of launching aerial drones to hit targets.
