Militaries, security forces, and even local police are woefully unprepared to deal with the biggest battlefield innovation in decades. Particularly effective are the fiber optic drones, which are immune to the easiest and most accessible countermeasure, which is jamming of the radio frequencies. They work so well that this cable is now one of the hottest commodities in the world.

Luckily, both industry and individual innovators have stepped up big to rapidly devise defenses against this. The global drone countermeasure (C-UAS) market, currently at $4.5 billion, is projected to triple within five years. Soon the threat at all levels will, I predict, be greatly diminished.
