The Ukrainian army has released a video that, according to this country, shows the first airlift of a wounded soldier from the front line using a drone in the world.

The 92nd Assault Brigade of Ukraine’s armed forces said that conducting a ground rescue operation was not possible because the injured serviceman was trapped among landmines and, at the same time, Russian drones were widely operating in the area.

According to the brigade, a six-rotor heavy drone that was controlled by a remote-operated operator was able to keep its operability during the operation “very difficult.”
