My understanding of experts I've read over years:
Western militaries, at least, have for over a decade worked on keeping humans 'in the loop', for the obvious moral reasons and also for effectiveness - human-machine teaming is considered much more effective than either humans or machines alone.
Yet they are developing autonomous machines because they don't believe they can rely on communications. The measure-countermeasure contest between communication and jamming leans too much toward the latter and it becomes a serious vulnerability: The machine army could be entirely shut down by simply jamming communications.
