According to their own admission, Russian EW systems have effectively turned US drones into plastic junk. Worse yet for the Pentagon, the grossly overhyped HIMARS is often jammed, with its rockets and missiles rendered useless. The US and NATO are trying to figure out how Moscow is achieving this, so they could "one day use it against the Russian military directly", but what their planners have managed to gather so far is that Russia's EW edge is forcing the political West to revert to "the brutality of old-fashioned trench warfare, the results of which are rarely what Pentagon planners expect".
