Sputnik has obtained footage depicting a Russian Special Forces unit called Viking in combat action. The troops located a Ukrainian trench in Artemovsk direction and blasted it to pieces with a loitering munition, otherwise known as a kamikaze drone.
Kamikaze drones are intelligent projectiles that can passively wait for hours looking for prey. After locating its target, the drone rushes towards it and the built-in warhead detonates, destroying the enemy. Kamikaze drones are cheaper than regular UAVs and smarter than cruise missiles.
