motorcycles can navigate bombed terrain, your fiber optics cables will be torn...

I can see the following technology replacing motorcycles for communication:

(works up to 20-30km, a bit more if needed)

a) preinstall your fiber optic cable between points A and B (say AA platforms that need/want coordination for distributed passive/multistatic tracking of intruders)

b) when it is torn, send a fiber optic drone from A to B and use its line to replace the torn one (those are flying in Ukraine with bomb payload, now just use its fiber optic reel, you can reuse the drone; not durable, but very cheap and fast repair of radiation-free communication lines)

Today's technology offers so many opportunities ...

Wouldn’t a WiFi mesh network be more reliable in war-torn areas? If you just need communication then actual “internet” is incidental and probably a security risk - just having a fairly secure local mesh network, with nodes covering hot-spot areas, seems like a good idea - it can cross areas where fiber isn’t reliable because of all the war, and it can potentially remove the need for some by-hand communication.

Wifi mesh makes sense in a densely populated area, not over mostly desert.

Also, communication over longer distances (even few km) will add so much latency that it will be unusable for coordinated AA targeting.

Furthermore, all that radiating will just invite bombs from the attacker.

Maybe I was not clear enough about the goal: not "robust command and control communication network", but more of:

quickly and temporarily set up a high-bandwidth low latency communication network to accomplish AA ambush using coordinated mobile passive sensors (a quick radar burst might for initial acquisition might be useful, but probably not necessary).
