While there is a role for UAVs the elimination of an uplink to a satelite pretty much renders them in effective.
I can see a situation where an "aircraft" gets flown into a battle area with the kit required for the battle team it carries and then gets abandoned as a throw away item while the kits splits into 4-5 pieces and starts manouvers, attacking an enemy.
Course if its all robotic one wonders when it will turn on its makers.
