Drone footage, most likely filmed by a Leleka-100 unmanned aerial vehicle (UAV), shows the engagement and destruction of a Russian Buk M-2 surface-to-air missile system by Ukrainian artillery.

The Leleka-100 is a domestically-developed Ukrainian UAV. It's primary roles are intelligence and observation. It can be used to identify and adjust fires onto target in realtime. The vehicle is extremely quiet, making it hard to detect by enemy ground units. The onboard avionics are housed inside a jamming resistant fuselage.
