It’s been obvious for a while unmanned drones will dominate war fighting at every level of engagement. Thousands of small anti personnel drones will be released in the near future.
The problem with drones in that role is the communication system. The Russians and the Ukrainians have been using jamming systems with very good results. I really believe that we will come up with jamming systems which can knock an ICBM out of flight.
Very powerful jamming systems will send all this back down to the individual infantry soldier carrying their weapons on their backs to put boots on ground. (Kind of like the Apocalypse says that each man will be fighting with his own weapons in Armageddon.)
