useless for many terestrial aplications, lasers are limited to line of site, and will have low mobility for the forseeable future.
it is just way too easy to develop drones that fly at ultra low altitude and automaticaly aproach targets from behind any line of site obsticle.
simple tactics of a randomised deek and dodge routine will also tax the tracking capabilities of the laser batteries ability to hit such small targets
remembering that the deeking and dodging
will be in 3D
and as the lasers will be the prime targets, these tactics will develop very
quickly, and the whole thing becomes self defeating
waste of time
