“Insane video of Russian anti-aircraft gunner losing control of a YakB-12.7 heavy machine gun,” one X user posted.

In the viral video, Russian troops appear to have mounted a rotary machine gun on a truck, a weapon typically fitted on Mi-24 attack helicopters.

In this particular video, the gun seems to have been bolted onto a truck bed to serve as a ground-based air-defence weapon to counter drones.

A video showing a Russian anti-aircraft gunner losing control of a powerful YakB-12.7 heavy machine gun during what appears to be a training exercise has gone viral.
