Perhaps tactics for defenders just have to be tweaked, but maybe this is the way things are:
In the face-off between expensive air defensive systems and lower cost offensive drones and low-flying missiles, the offense is winning.
My view is that in the face of swarming drone attacks that the traditional air defense systems designed for blue sky planes and missiles can't cope; and that our forward combat units should not be burdened with lugging around enough ground-based air defenses to deal with the new threat low to the ground in the air space near our companies and platoons that I dubbed the "brown skies."
Instead, as I proposed in Army magazine, we need air defense drones to shoot down the attacking drones in the low-level brown skies.
