They have suddenly discovered what engineers have been telling them for about 80 years, and theoreticians have known for 100+ years is actually true: directional beams that cannot realistically be distrupted + satellites out of reach + even if you can you can only take ALL satellites out of orbit (ie. including your own, not just the enemy's). So on future battlefields, everyone will have livestreaming.

Do governments and militaries even believe in the laws of physics? I mean that exactly this was going to happen (undisruptable radio comms + robots, on the battlefield) was perfectly predictable near ~about 1960, and it's an absolute miracle that it took so long to come to pass.

And even that is assuming you're only willing to believe in demonstrations. For physicists it must have been a theoretical certainty that this was coming before WW1 was done.
