The THOR III is man-portable, counter-radio-controlled improvised explosive device (IED) jammer built by Sierra Nevada Corp and employed by the U.S. Army, U.S. Marine Corps, and partnered Afghan National Army soldiers in Afghanistan. Sierra Nevada received the initial contract in December 2007. [1] This system uses three transceivers mounted on backpacks to jam radio-controlled IEDs; each of the three different transceivers jams a different frequency bandwidth (Low, Mid, and High). [2] [3]

Improvised explosive device homemade bomb

An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs.

Explosively formed penetrator

An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively. As the name suggests, the effect of the explosive charge is to deform a metal plate into a slug or rod shape and accelerate it toward a target. They were first developed as oil well perforators by American oil companies in the 1930s, and were deployed as weapons in World War II.

Joint Improvised-Threat Defeat Organization

The Joint Improvised-Threat Defeat Organization (JIDO) is a combat support organization of the U.S. Department of Defense (DoD) organization under the Defense Threat Reduction Agency (DTRA) that deals with improvised threats such as the improvised explosive device (IEDs) and small unmanned aerial systems (sUASs). JIDO was born from the Joint IED Defeat Organization (JIEDDO) established in 2006, which focused on IEDs. JIDO's mission is to "enable Department of Defense actions to counter improvised threats with tactical responsiveness and anticipatory acquisition in support of combatant commanders' efforts to prepare for, and adapt to, battlefield surprise." This mission supports counter-terrorism, counter-insurgency and other related mission areas including Counter-IED.

Counter-IED efforts

Counter-IED efforts are done primarily by military and law enforcement with the assistance of the diplomatic and financial communities. It involves a comprehensive approach of countering the threat networks that employ improvised explosive devices (IEDs), defeating the devices themselves, and training others. Counter-IED, or C-IED, is usually part of a broader counter-terrorism, counter-insurgency, or law enforcement effort. Because IEDs are a subset of a number of forms of asymmetric warfare used by insurgents and terrorists, C-IED activities are principally against adversaries and not only against IEDs. C-IED treats the IED as a systemic problem and aims to defeat the IED System.

Counter-IED equipment

Counter-IED equipment are created primarily for military and law enforcement. They are used for standoff detection of explosives and explosive precursor components and defeating the Improvised Explosive Devices (IEDs) devices themselves as part of a broader counter-terrorism, counter-insurgency, or law enforcement effort.

The Rhino Passive Infrared Defeat System was an early detonation Counter-IED system. It was mounted to the front of a vehicle and used heat to prematurely detonate any hidden improvised explosive devices (IEDs) while the vehicle was at a safe distance away from the blast. It was developed by the Joint Improvised-Threat Defeat Organization (JIEDDO) in 2006 during the war in Iraq to counter the rise of IED-related deaths.

The Improvised Explosive Device Countermeasure Equipment (ICE) is a vehicle-mounted electronics-based jamming system that uses low-power radio frequency energy to thwart enemy improvised explosive devices (IEDs). The radio frequency energy it emits blocks the signals broadcast by radio-controlled detonators, such as cell phones and cordless telephones, that would otherwise trigger the hidden IED to explode. ICE was developed by the Army Research Laboratory (ARL) at White Sands Missile Range and the Physical Science Laboratory (PSL) at New Mexico State University in 2004 to counter the rising IED threat in Iraq. Due to the urgent demand for counter-IED equipment, ICE was designed and built within three weeks and was provided to troops in less than six months after the project started.
