The money is expected to be given to the Joint Improvised-Threat Defeat Organization (JIDO), the Pentagon’s special office dealing with improvised explosive devices, Defense News reports.

By the end of 2016, the JIDO with a budget to deal with new IED threats that emerged during the campaigns in Afghanistan and Iraq, will become a permanent establishment under the Defense Threat Reduction Agency.

The new agency is set to deal with the full range of improvised threats emerging around the world, yet its priority is to engage IED and drone threats posed by Islamic State (IS, formerly ISIS/ISIL) and those that emerge in the course of operation Resolute Support, the US assist and advise mission to Afghanistan’s security forces.

“This effort will fill critical capability gaps defined in the Counter-Unmanned Aerial Systems Joint Urgent Operational Needs Statement (JUONS) to support counter-improvised explosive devices (C-IEDs) and improvised threat capability requirements in support of Counter-Islamic State of Iraq and the Levant and Resolute Support (C-ISIL/RS) missions,” Defense News quotes the reprogramming document.

The program will focus on creating a means to detect and defeat small and tactical unmanned aerial systems posing a“direct threat to US and coalition forces,” the document says.

“We expect their use to increase because commercial unmanned aerial vehicles have become very accessible,” Small acknowledged, adding that IS militants in Iraq have already been spotted using drones to deliver with precision small-sized handmade explosive devises. “There are known efforts by ISIL to grow this capability,” Small said.

If Congress approves the reprogramming funds, the JIDO’s counter-drone research will bear fruit within “zero to two years,”Small said.

Still, the incidence of armed drones by terrorists is considered low now, the spokesman acknowledged, stressing that so far the drones are more commonly used by terrorists as a reconnaissance tool. The stats on use of armed drones by IS remain classified.

According to Small, Islamic State has been using drones for four definite purposes, namely tactical observations, monitoring enemy response to IS attacks, guiding Vehicular Borne Improvised Explosive Devices (VBIED) and collecting propaganda material.

Monitoring and observation missions require the use of full motion video, Small noted. He said IS attacks employing VBIEDs have become routine and “highly sophisticated.”

Exactly what counter-drone means the JIDO will develop is top secret to “keep the enemy guessing,” Small said.
