This paper describes methods of eliminating Unmanned Aerial Vehicles (UAV) nondestructively, using Electronic Warfare Methods. The aim is to introduce certain methods of UAV detection and elimination in a complex environment and terrain, e.g., in an urban and battlefield environment, that will result in finding the control device position and the UAV itself. Neural networks, cyber penetration elements, and wireless network scanning programs are all used to address this issue. The output of this article is a new concept of a comprehensive solution, which can be implemented into the existing complex system of electronic defence against UAVs, e.g., within the allied base. Conclusions will be also used to further improve the above-mentioned topics at the authors' workplace, within the frame of long-term projects and specifically as a part of solutions applicable to the force protection of combat support units, namely field artillery, which is described here in detail.
