So something like lightly armored rocket artillery with a screen of antipersonnel/reconnaissance drones that could paint targets for guided rockets.
Not only that. The drones themselves could act as munitions. They could clamp themselves onto something like a main battle tank cannon and set off a shaped charge.
This might work well until you need to take enemy air force into account.
Make the drones small enough, and make them fly low enough, and it won't be as much of an issue. Also, this is why you have your own air force and surface to air missiles.
I was thinking about air force blowing up lightly armored rocket artillery. Also drones make natural target for automatic radar or lidar aimed weapons. I suspect there will be a race to make drones nearly invisible to that form of targeting in a few years as armies around the world equip them.
