Drone team has bombed tanks, armoured fighting vehicles and ammunition dumps but still Russians are on the move

At night, Sasha and his drone team go in search of the enemy. They set off in a dirt-covered vehicle towards the eastern Ukrainian city of Mariinka, occupied by Russia since December. They unload a large drone. And then they fly it in darkness across the frontline, above a ghostly landscape of fields and ruined houses, towards the twinkling city of Donetsk. The drone carries a deadly arsenal of six grenades.

Sasha, who uses the call sign “Tourist”, has bombed more than 100 pieces of Russian military equipment. The list includes tanks, armoured fighting vehicles and self-propelled guns, as well as hidden ammunition dumps. Russian howitzers are another key target. Recently his special operations unit forestalled a large-scale attack. It spotted seven Russian tanks massed for a dawn raid and disabled two of them.
