U.S. Troops face all new threat as ISIS deploys flying IEDs. Drones are now pretty much commonplace. Coming soon to a neighborhood near you. If Amazon can use them to deliver books to your home, it’s only natural that they could be used as weapons.

Marine Corps Times:

Drone warfare recently entered a new chapter in which America’s adversaries can successfully deliver explosives via cheap, commercially available unmanned aircraft, challenging the U.S. military to go on the defensive.

An explosives-laden Islamic State drone killed two Kurdish peshmerga troops and wounded two French paratroopers early this month in the vicinity of Erbil, Iraq, Popular Science reported. It is believed to be the first time the militant group has inflicted such casualties.

The drone exploded while it was being inspected after being shot down, Air Force Col. John Dorrian, Operation Inherent Resolve spokesman, confirmed Wednesday.

“We’ve seen several reports about ISIS use of commercial off-the-shelf drones, including instances where they’ve used these capabilities to deliver explosives,” Dorrian told reporters in a Pentagon teleconference from Baghdad, Iraq.

“It’s a threat that’s not new to the area,” he said, calling the attack a Trojan Horse-style attack.

Nor is it the first time ISIS has tried.

There are at least two other instances over the last month that ISIS has tried to use drones to deliver explosives, according to The New York Times.

The two peshmerga troops were killed Oct. 2, according to a U.S. official, who said the drone looked like a Styrofoam model plane that was taped together in a very rudimentary style, according to The Associated Press. The official said it appeared to be carrying a C4 charge and batteries, and may have had a timer on it, AP reported. More
