Human error when approaching the wreckage of Russian drones can lead to death. Increasingly more Russian "Gerbera" drones, which were previously used for reconnaissance, have begun to be found with warheads inside, says Ukrainian electronic warfare expert Serhii Beskrestnov, also known as "Flash". 

At the same time, Russian forces use an extremely dangerous scheme in which the detonator is activated during the drone's flight, as a result of which it triggers on impact. 

Therefore, transporting a fragment in a car/trunk/bag is deadly dangerous: a bump on the road or shaking can cause an explosion.

From a reconnaissance drone to a lethal trap

He also showed the warhead with a detonator that he found inside one of the "Gerberas".

"In one photo the warhead OFBCh-2 with a UZ-2 detonator. In the second photo the warhead's connection inside the UAV," he notes.

Why "cutting the wires" won't save: detonator set to combat-ready

Flash explains that a signal from the flight controller goes to a relay, which closes and supplies voltage from three batteries to the detonator connector. This is likely to occur according to an altitude criterion.

"This signal does not detonate the warhead, as many think. This signal sets the detonator to combat-ready. Such a scheme allows the crew that launches the "Gerbera" not to take risks," the expert explains.

That is, activation of the detonator occurs during flight. On impact with the ground, the detonator triggers, and the warhead explodes. 

At the same time, he warns: the detonator may not trigger during a smooth landing of the drone; however, it remains in the combat-ready position. That is why such a drone must under no circumstances be thrown or transported in a trunk.

"The main mistake that can cost lives: it is not an electric detonator. Do not think that you cut the wires or disconnected the connector, and everything will be fine. The warhead's detonator is already in the combat position," emphasizes Flash.

This detonator also has self-destruction contacts, "so what nastiness the Russians may come up with in the future, no one knows," the specialist added.

Therefore, if a person finds such a drone, follow the official warnings of rescuers and do not approach the wreckage, do not transport it, and do not try to disassemble it.
