Someone managed to shutdown an UK airport with a "industrial drone". Assuming that the drone operator is a professional with a tailored drone for this purpose, what options are there to take it down. Does IRST/EOTS work on small drones and are there any other way to detect a 20kg drone flying in treetop height.
What ways are there to disable the drone when found?There where a discussion on reddit on sniper vs shotgun where shotgun lacked range and the snipers could inflict collateral damage. I think that a traditional airbust AA gun or xm25 with timed/proximity fuse would work best.
