The company "Roboavia" presented a strike drone called "Surprise". The quadcopter is capable of carrying two 82mm mines.
The drone can be folded and transported in a backpack, but its mass is decent - 24 kg. The range of the drone in the strike version (that is, with attached mines) is 10 km, while it has a power reserve to return to base.
Why the drone was called "Surprise"? The thing is that the drone flies at an altitude of 400 meters, and the enemy does not see or hear it.
The "Surprise" is equipped with a video camera, a thermal imager, a system for correcting the drop of ammunition. The drone can be controlled both from a ground control station and just a joystick.
