> Line of sight free space optics can be immune to many many forms of jamming.
I’m a bit of two minds about this. Obviously jamming resistant high bandwidth communication enables some scarry possibilities.
But the lack of it is what drives and will drive militaries around the world to put more and more autonomy into weapons. It doesn’t matter what kind of treaties we write on paper to prohibit technologies. During a war if your drones/loitering munition are less effective than those of your enemies because your control signals are jammed you will give in and make your weapons find their target without that control signal. That leads to an arm race of ever more sophisticated autonomous weapons. That is scarry for many reasons, and probably a worse outcome for all of us.
On the other hand if communication is possible that puts a leash on this dynamic and ensurers that a human mind can remain in the loop. So… maybe being better at jamming resistant communication is actually better for humankind?
Ukraine's drones are already partly automated because of the jamming environment: they can visually lock the drone onto a target from up to 10km away.[0][1] They're also using drones that trail a fibre optic over several kilometres to avoid jamming.[2]

This capability is basically a reinvention of the walleye television bomb, which locked onto targets using edge detection on a signal from an internal television camera. 1960s technology.
Wire guided is still the primary means of guiding torpedos from submarines, because it gives you an unjammable, un-interceptible, consistent communication interface, and in torpedoes the wire spools out for tens of kilometers.
If you want something really cool, look up old fashioned TV guidance. We built weapons that guided based a TV signal, and edge detection in that signal. In 1958.

I'm a bit more pessimistic than that. I think the driver for autonomy will be that the speed at which things happen on the battlefield. People being attacked with automated weapons might not be able to make response related decisions fast enough. The automation will be in place to enable a rapid response. It will become an arms race involving speed of attack and response. It will be the military equivalent of high-frequency trading, involving things like swarms and directed energy weapons.
I got seriously terrified by reading a PKD SF story at 15 about the few surviving humans hiding from war drones still hunting people long after the war had ended.
Haven't read the book, but I did see "Screamers". Wikipedia says: "Future Imperfect: Philip K. Dick at the Movies, writes that the film is more faithful than most other adaptations".
I can't comment on whether that's true, but the movie still haunts me. Odd, since as Wikipedia says "it received a mixed critical reception and failed at the box office". There was nothing mixed about my reception of it.
Similar but reverse, I felt unfortunate to have read the novelette after watching Terminator because part way in the story I thought - this is almost all of the AI/self replicating autonomous robot points of the Terminator movie just without the time travel. The movie addition of time travel adds a bit of hope to an otherwise totally bleak story resolution.
"People with blue and yellow patches are the enemy. I won't be able to communicate with you after you leave the forward base, but you need to navigate about 1 mile southwest then kill the people you find with a blue and yellow patch for as long as you can."
Then the quadcopter/Atlas/Spot/a Terminator/a tank driven by AI starts rolling across the landscape, while humans flagged as suspicious by Google because we lack sufficient tracking data in our browsers fill out reCaptcha images that say "Select all images that contain [soldiers] in this set."
Nearby, a scared local child distracts themselves from the distant horrors by drawing a picture of the sun in the sky with their crayons.
Some time later, the robot is able to transmit back a few bytes of telemetry to base, which publishes a press release that describes the number of enemies slain.

This sounds like you would also be in favor of backdoored encryption. I disagree. It's a tool / improvement like any other, how you use it makes it scary.
BTW this is nothing new, it's just packaged nicely and (I assume) massively improved technology. DIY and open source solutions were possible in 2001 https://en.wikipedia.org/wiki/RONJA (static ones tho)
