I suppose they mean you won't need a drone pilot, which takes training and takes a soldier off the battlefield in terms of them needing to have on a headset and can't fire a conventional weapon at the same time. I don't think it will come to the war so quickly though, it's the least of the problems at the moment for Ukraine that badly needs long range missiles, mine clearing equipment and F16s.
FPV pilots need special training & jamming could interrupt the control link.
A fully autonomous drone is a nightmares inducing option that just does not have these downsides. For extra inhuman points you could have it sleep in a box & launch on trigger or timer.
Like the hunter seeker from Dune, just without a pilot, lightning fast & with a RPG7 round stripped to it.
Oh those rose colored visions of future utopia people had in the past. ;-)
