Drone-Killing Gun Spotted at US Base in Iraq
[DefenseTech] The tweet was subsequently cited in an article by Thomas Gibbons-Neff, a reporter for The Washington Post, who reported the weapon is probably being used by American troops to target small reconnaissance drones operated by the Islamic State in Iraq and Syria, or ISIS.

The weapon, which the company makes clear isn't authorized by the Federal Communications Commission and thus isn't available for sale in the U.S., uses radio waves to cut the link between the drone and its controller.

One of the old-style anti-tank rifles of the 1920s and 1930s would presumably work well here, with a scope or some sort of electronic aiming.
