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).
