they won't, and by that I mean they won't be able to, either outside countermeasures will stop the drones, or the drones will reach their target, they are ambush units, they will hit squads in bunks and trenches when they are sleeping, pissing, shitting or otherwise indisposed, it will ram into your ATV or otherwise from an angle you won't see coming, and will have seconds to react to.
mind you, many will fail, but the problem, the genius and the horror of the small drone, is that its cheap, its not a person it costs a couple of hundred bucks for the whole kit, a failure is nothing, success is huge, each wounded or dead soldier is 100x the cost, the morale oss of soldiers being maimed by small kid toys is huge.
Dreaming up some wunder-gun for soldiers to have for drones is retarded, the wunder-gun will probably cost 100x the cost of a drone, and one of drone will eventually kill the soldier holding the wunder-gun. the amount of use drones will have in coming wars is immense, and most of the purposed countermeasures are much more expensive than the drone, or just won't work, any "jammer" system will give itself away by its very nature and be artilleried, trading your complex drone jammer for a single artillery shell, and so on and so on.
America can, by and large foot the bills for these insane exchanges, but they will indeed foot them, bodies and money by the buttload, if and when we go to a more serious war.
