"they can burn unmanned aerial vehicles (UAVs) in the air at a relatively low cost, compared with shooting them down with bullets or artillery." [relatively low cost]
Drone warfare's strategic appeal rests on forcing defenders to spend expensive interceptors against cheap attackers. Laser systems with low per-shot costs — essentially electricity — invert this calculus. The article's framing of cost efficiency as a primary selling point signals that militaries are explicitly designing around this economic dynamic, not just the technical one. If man-portable laser systems proliferate, the mass-drone saturation tactic used in conflicts like Ukraine-Russia loses its cost-asymmetry advantage, potentially reshaping offensive drone doctrine globally.
