Drones 'Hunt' Civilians in Kherson
theguardian.com> The repurposed Mavic drones, made in China for photography and videos, are controlled on radio frequencies that Ukraine’s anti-drone systems cannot block, and are too small, too numerous and fly too low for traditional air defences to pick up.
AFAICS, the Mavic drones use 2,4 and 5 Ghz control frequencies. Why they couldn't they be blocked in a warzone?
