I pushed a somewhat over lengthy reply above, but short version for this context is that GPS/FPV in current EW/EMI regime has unacceptable loss rates in UA (see also many many grounded / "spared" US origin "precision" weapons because GWOT era crap has totally vanilla gps), which means fiber, which means the range is back to within 20-40km. Unless the target is low risk/value, or on the move AND low value, or (most likely) you have truly bananas amount of drone magazine to burn through. Laser mesh networks I think are also being tried, but again, that's a bunch of drones. Another downside of fiber is the same downside as laser sighting - there is an arrow painted on the ground back to your position. The fiber is no viz to your eyeball, but not to dynamic filters on your drone's EOIR. That will get back to counterbatteries or enemy fiber drone - and if their first arty shot is a guided arty (tube or rocket) you don't get the warning of ranging "framing" shots. The WW2 experience mindset couldn't be a worse metaphor here.
