It might prove to be a great last line of defense, but close to the front, it will be targeted by artillery or over whelmed by drones.

The world isn't ready for Drone Warfare, I can't imagine the reactions of Western nations if they had to face what Ukraine faces every day. 200 drones is what flies in a minute along active locations on the front lines of Ukraine.

Couldn't you just fly low so that you'd be within the energy weapon's dead zone? I mean it doesn't look as if it can target anything flying at a depression less than 0°. Seems a few cheap fiber optic drones with a mortar lazily strapped to it and flying low could easily render this useless.
