You could drop hundreds of autonomous drone by air, make them land somewhere and wait in standby until they get activated or detect a threat.
They scale massively because 1 guy with 100 rifles won't do much more than 1 guy with 1 rifle, 1 guy with 100 trucks won't move faster than 1 guy with 1 truck. 0 guy with 100 drones would potentially kill 100 guys simultaneously for cheap since switchblade style drones are glorified DJIs with a grenade straped at the front
I suspect we will start seeing the first true drone swarm deployments in Ukraine over the next couple years. The world is simply not ready for how horrifying it will be. These things can be manufactured for a few hundred bucks a piece. Sony can pump out 10 million PlayStations in a few months. What happens when that kind of logistics and manufacturing is applied to kamikaze drones? You get swarms of tens of thousands of them. The entire future of land warfare from this point on will be an arms race between drone swarms. And the swarms will take on combined arms aspects; there will be AA, AT, AP, incendiary, electronic warfare, observation, and hunter-killer variants. Winning wars in the future will consist of choosing the correct size and makeup of your swarm to counter the enemy's capability.
If anything, we see from the conflict in Ukraine that keeping smart weapons supplied in a modern conflict it a huge effort that needs a lot of interconnected players.
