Their use has been interesting, from early adaptions used to drop grenades, to spotters for artillery, to suicide missions. They've definitely changed the face of warfare. The Ukrainians led the way at the beginning, but it seems Russia learned fast and adopted their use widely.

The naval ones have been bloody successful too and I can see autonomous seaborne drone swarms replacing mines to deny access to areas.

Did you all see the terminator 1 looking tracked land drones Russia used recently? Fitted with grenade launchers, sent at the front lines to sew chaos, followed, of successful by infantry. That'll evolve further in the future too. Scary stuff.
