The newest type of drone jammers

Despite the resemblance to guns, jammers don't literally shoot the drones. The drone wouldn't just drop to the ground. Instead, it should hover in place within an invisible fence created by the jammer. This makes it easier to catch illegal drones.

Swiss police were pictured this week in Davos testing anti-drone jammers, which resemble massive machine guns, as part of security preparations for the World Economic Forum.

An apparently different type of anti-drone weapon spotted in Iraq is Perfectjammer, made by Battelle, which resembles an assault rifle but features a directed energy frequency jammer mounted on the frame. It has a range of about 400 yards and works by disrupting the links to the drone controller or GPS device.
