Here's how China is battling drones

The country is already selling truck-mounted laser cannons: the Low Altitude Guard and the higher powered Silent Hunter. The Silent Hunter uses a laser to zap ground and air targets up to 4 kilometers (about 2.5 miles) away, and at closer range is powerful enough to threaten lightly armored vehicles. The government used the Silent Hunter to protect the September 2016 G20 summit in Hangzhou, Zhejiang province. Such "hard kill" systems would be necessary to fight future autonomous drone threats, which won't be so easily disabled by jammed communications. The current use of drones by militaries and everyday citizens, coupled with the promise of AI-enhanced and networked platforms, suggests that we will see more technology and incidents of the kind shown off at Wuhan.
