Nothing we have now (publicly) is going to do a damn against a shipping container full of 2-5 lb drones each carrying 1 lb of C4 in a swarm with cheap off the shelf sensors going 100 mph nap of the earth in a distributed pattern. And that is currently entirely doable with off the shelf drones using existing software and published techniques for peanuts. Add in some decent programming and logistics talent, and that is a huge problem.
