>Is this really the state of warfare now, or is the situation in Ukraine is somehow exceptional, and we are unlikely to see it repeated elsewhere?
yeah, as long as lads have a 1-2km range simple hand-held/backpack radar (not too difficult to make in the field either if required and the operator knows what he's doing) with a shotgun with birdshot/7mm buckshot no drone will be able to resist as they fly relatively low (enough to get hit by birdshot/buckshot)
if you get in a squad of 10, 2 lads with their main rifles, disposeable AT and their shotguns as their secondaries to protect against drones, you're good to go (use some ultra-light semi-auto shotguns with 6-8 shells in the mags and ggez - MP-153 as example for the ruskies)
for convoys and such, use a shotgun with mags that can allow ~35 shells to protect against drone sworm attacks (at least 2 such shotguns per convoy)
also, those saying that "radar systems are complex and shite" - a guy literally trained AI to radiolocate individuals accurately with a WiFi router; it ain't hard, it's just a bit of tinkering and engineering and you'd be good to go - a couple of plastics, copper, big old batteries and a reporpused old (nokia, samsung) phone and boom, you're good to go
