Explosives are just a payload (like any other payload you can attach to a drone), either independent from the whole system or activated through a simple relay. You can see ArduPilot is the ground station, where you can easily customize such switches. The distance is only about the wire/fiber; obviously, fiber is lighter, hence the longer distance for the drone to carry.

Ten miles is pretty impressive, but TOW missiles are from the 70s.

The Ruhrstall X-4 [1] had five and a half kilometers of wire 80 years ago, along with a 20kg warhead and an acoustic proximity fuse.
