Russia’s advanced jamming technology and electronic warfare capabilities are well known. The conflict in eastern Ukraine allowed the separatists supported by Russia to benefit from Russia’s capabilities and support, and the Ukrainian armed forces gave the U.S. armed forces a unique view of Russia’s capabilities.
