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]

Bomb disposal Activity to dispose of and render safe explosive munitions and other materials

Bomb disposal is an explosives engineering profession using the process by which hazardous explosive devices are rendered safe. Bomb disposal is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the public safety roles of public safety bomb disposal (PSBD) and the bomb squad.

Improvised explosive device Unconventionally produced bombs

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.

LAV III Type of Infantry Fighting Vehicle

The LAV III, originally named the Kodiak by the Canadian Army, is the third generation of the Light Armoured Vehicle (LAV) family of infantry fighting vehicles built by General Dynamics Land Systems – Canada (GDLS-C), a London, Ontario based subsidiary of General Dynamics that first entered service in 1999. It was developed in Canada as modification of the Swiss Mowag Piranha IIIH 8x8 and is the primary mechanized infantry vehicle of both the Canadian Army and the New Zealand Army. It also forms the basis of the Stryker vehicle used by the US Army and other operators.

Explosively formed penetrator peoples

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.

52nd Ordnance Group (EOD)

The 52nd Ordnance Group (EOD) is the command and control headquarters for all U.S. Army Explosive Ordnance Disposal (EOD) Battalions and Companies located east of the Mississippi River in the Continental United States (CONUS). The current command team consists of Colonel Gregory J. Hirschey and Command Sergeant Major Michael C. Gray. Their command covers 184th and 192nd Ordnance Battalion (EOD), as well as the 63rd Chemical Company (CBRN). Subordinate units maintain EOD Response Teams, which evaluate, render safe, and remove conventional, chemical/biological, or nuclear ordnance, or improvised explosive devices (IEDs) which pose an immediate threat to public safety. While subordinate units are trained and equipped for combat operations, they may also support a variety of peacetime missions, to include range surface clearance operations of active U.S. Army installations, EOD and UXO operations in support of civilian law enforcement agencies, and support to the U.S. Secret Service for protection of VIPs.

Joint Improvised-Threat Defeat Organization

The Joint Improvised-Threat Defeat Organization (JIDO) was 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 Strategy in C-IED

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 threat networks themselves.

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.

The Light Armoured Vehicle (LAV) is a series of vehicles built by General Dynamics Land Systems – Canada (GDLS-C), a London, Ontario based subsidiary of General Dynamics. First entering service in 1976, it has undergone a number of different upgrades and improvements over time which are denoted by different "marks" such as the LAV II, LAV III etc. It continues to form the backbone of the Canadian Army's combat vehicle fleet. The LAV series of vehicles exist in a number of different variants and are used in a number of different roles such as Armoured Fighting Vehicles, Infantry Fighting Vehicles, Armoured Engineer Vehicles, Command Posts, Ambulances, Repair and Recovery vehicles, etc.
