Munitions rigged for an IED discovered by Iraqi police in Baghdad, November 2005.

An improvised explosive device (IED, sometimes referred to as a roadside bomb) is a bomb constructed and deployed in ways other than in conventional military action. They may be partially comprised of conventional military explosives, such as an artillery round, attached to a detonating mechanism.

Background

An IED is a bomb fabricated in an improvised manner incorporating destructive, lethal, noxious, pyrotechnic, or incendiary chemicals and designed to destroy or incapacitate personnel or vehicles. In some cases, IEDs are used to distract, disrupt, or delay an opposing force, facilitating another type of attack. IEDs may incorporate military or commercially-sourced explosives, and often combine both types, or they may otherwise be made with home made explosives (HME). The word pyrotechnic (literally meaning fire technology) refers to any chemical explosive device, but especially fireworks. ... hey hey you no i rock at soccer cuz no i made the school team!! yay me aka katelyn ♥ Incendiary devices or incendiary bombs are bombs designed to start fires or destroy sensitive equipment using materials such as napalm, thermite, chlorine trifluoride, or white phosphorus. ... Chemical tanks in Lillebonne, France Chemical industry includes those industries involved in the production of petrochemicals, agrochemicals, pharmaceuticals, polymers, paints, oleochemicals etc. ...


An IED typically consists of an explosive charge (potentially assisted by a booster charge), a detonator, and an initiation system, which is a mechanism that initiates the electrical charge that sets off the device. IEDs are extremely diverse in design, and may contain many types of initiators, detonators, and explosive loads. In some cases, IEDs also contain metal objects such as nails or ball bearings (known as shipyard confetti after the metal waste found in the shipyards of Belfast). IEDs are triggered by various methods, including remote control, infra-red or magnetic triggers, pressure-sensitive bars or trip wires. In some cases, multiple IEDs are wired together in a daisy-chain, to attack a convoy of vehicles spread out along a roadway. A detonator is a device used to trigger bombs, shaped charges and other forms of explosive material and explosive devices. ...


IEDs made by inexperienced designers or with substandard materials may fail to detonate, and in some cases actually detonate on either the maker or the emplacer of the device (these unintended early detonations are known as pre-detonations or "own goals" if the placer is killed in the detonation). However, some groups have been known to produce sophisticated devices that are constructed with components scavenged from conventional munitions and standard consumer electronics components, such as mobile phones, washing machine timers, pagers, or garage door openers. The sophistication of an IED depends on the training of the designer and the tools and materials available.

An own goal occurs in goal-scoring games when a player scores a goal that is registered against his own team. ... Munition is often defined as a synonyn for ammunition. ... This article is about the engineering discipline. ...


The majority of IEDs use conventional high-explosive charges as their explosive load. However, the threat exists that toxic chemical, biological, or radioactive (dirty bomb) material may be added to a device, thereby creating a host of other life-threatening effects beyond shrapnel, concussive blasts and fire normally associated with bombs.

A vehicle borne IED, or VBIED, is a military term for a car bomb or truck bomb. These are typically employed by suicide bombers, and can carry a relatively large payload. They can also be detonated from a remote location. VBIEDs can create additional shrapnel through the destruction of the vehicle itself, as well as using vehicle fuel as an incendiary weapon. For other uses, see Car bomb (disambiguation). ...

Since these devices are improvised, there are no specific guidelines for Explosive Ordnance Disposal (EOD) personnel to use to positively identify or categorize them. EOD personnel are trained in the rendering safe and disposal of IEDs. The presence of chemical, biological, radiological, or nuclear (CBRN) material in an IED requires additional precautions. As with other missions, the EOD operator provides the area commander with an assessment of the situation and of support needed to complete the mission.

Countermeasures

Military forces and law enforcement personnel from around the world have developed a number of Render Safe Procedures (RSP) to deal with IEDs. RSPs may be developed as a result of direct experience with devices or by applied research designed to counter the threat. The claimed effectiveness of remote jamming systems, proven or otherwise, has caused IED technology to essentially regress to command-wire detonation methods. [4] These are physical connections between the detonator and explosive device and cannot be jammed. However, these types of IEDs are more difficult to emplace quickly, and more readily detected. Render Safe consists of proceedures, tools and methods to render an IED or Ordnance item incapable of high-order detonation. ...


Military forces from Canada, United Kingdom, Israel, Spain and the United States are at the forefront of counter-IED efforts, as all have direct experience in dealing with IEDs used against them in conflict or terrorist attacks.


Technological countermeasures are only part of the solution in the effort to defeat IEDs; experience, training and awareness remain key factors in combating them. For example, there are visual signs that may suggest the presence of an IED, such as recently turned-over soil or sand by a road, or an abandoned vehicle beside a road. Recognizing these telltale signs may be as valuable as having sophisticated detection equipment.


History

World War II

One of the first examples of coordinated large-scale use of IEDs was the Belarusian Rail War launched by Belarusian guerillas against the Nazis during World War II. Both command-detonated and delayed-fuse IEDs were used to derail thousands of German trains during 1943–1944.

Northern Ireland

Throughout The Troubles, the Provisional IRA made extensive use of IEDs in their campaign against the British army.

Roadside bombs were extensively used by the Provisional IRA. Typically, a roadside bomb was placed in a drain or culvert along a rural road and exploded by remote control when British Army or other security forces vehicles were passing. The most lethal example of these attacks came in 1979, when 18 British soldiers were killed by two culvert bombs in the Warrenpoint ambush. As a result of the use of these bombs, the British military had to stop transport by road in areas such as South Armagh, and use helicopter transport instead. In the 1980s and 1990s, all culverts were welded and concreted shut, so that explosives could not be placed in them.

In the early 1970s, at the height of the PIRA campaign, the British Army unit tasked with rendering safe IEDs, 321 EOD, sustained significant casualties while engaged in bomb disposal operations. This mortality rate was far higher than other high risk occupations such as deep sea diving, and a careful review was made of how men were selected for EOD operations.

The IRA came up with ever more sophisticated designs and deployments of IEDs. Booby Trap or Victim Operated IEDs (VOIEDs), were commonplace. The IRA engaged in an ongoing battle to gain the upper hand in electronic warfare with remote controlled devices. The rapid changes in development led 321 EOD to employ specialists from DERA, the Royal Signals, and Military Intelligence. This multi-unit approach led to the development and use of most of the modern weapons, equipment and techniques now used by EOD Operators throughout the rest of the world.

Vietnam

IEDs were used during the Vietnam War by the Viet Cong against land- and river-borne vehicles as well as personnel.[5] They were commonly constructed using materials from unexploded American ordnance.[6] 33 percent of U.S. casualties in Vietnam and 28 percent of deaths were officially attributed to mines; these figures include losses caused by both IEDs and commercially manufactured mines.[7] Combatants Republic of Vietnam United States Republic of Korea Thailand Australia New Zealand The Philippines National Front for the Liberation of South Vietnam Democratic Republic of Vietnam People’s Republic of China Democratic Peoples Republic of Korea Strength US 1,000,000 South Korea 300,000 Australia 48,000...

The Grenade in a Can was a simple and effective booby trap. A hand grenade with the safety pin removed and safety lever compressed was placed into a container such as a tin can, with a length of string or tripwire attached to the grenade. The can was fixed in place and the other end of the string stretched across a path or doorway opening and firmly tied down. Alternatively, the end of the string could be attached to the moving portion of a door or gate. When the grenade was pulled out of the can by a person or vehicle placing tension on the string, the spring-loaded safety lever would release and the grenade would explode. Viet Cong forces would place grenades (with the pin pulled) in empty food cans that had been discarded by American forces, as a cheap booby trap for the resourceful Viet Cong.

Tripwire is a company based in Portland, Oregon which produces change auditing software. ...


The rubber band grenade was another booby trap. To make this device, a Viet Cong guerilla would wrap a strong rubber band around the spring-loaded safety lever of a hand grenade and remove the pin. The grenade was then hidden in a hut. American and South Vietnamese soldiers would burn huts regularly to prevent them from being inhabited again, or to expose foxholes and tunnel entrances, which were frequently concealed within these structures. When a hut with the booby trap was torched, the rubber band on the grenade would melt, releasing the safety lever and blowing up the hut. This would often wound the soldiers with burning bamboo and metal fragments. This booby trap was also used to destroy vehicles when the modified grenade was placed in the fuel tank. The device would be triggered when the rubber band would be eaten away by the chemical action of the fuel, releasing the safety lever and detonating the grenade.

Another interesting hand grenade variant was the mason jar grenade. The safety pin of hand grenades would be pulled and the grenades would be placed in glass ball mason jars which would hold back the safety lever. The safety lever would release upon the shattering of the mason jar and the grenade would detonate. This particular variant was popular with chopper crews, which would use them as improvised anti-personnel cluster bombs during air raids. They were easy to dump out of the flight door over a target and the thick Ball Mason glass was resistant to premature shattering.


Afghanistan

Following the invasion of Afghanistan by the USSR on 27 December 1979, the Afghan Mujahideen were supplied with large quantities of military supplies from many Muslim states and from the United States. Among those supplies were many types of anti-tank mines. The Afghan Mujahideen often removed the explosives from several foreign anti-tank mines, and combined the explosives in tin cooking-oil cans for a more powerful blast. Often the foreign anti-tank mines were enclosed in plastic containers, making them difficult to detect. By combining the explosives from several mines and placing them in tin-cans, the Afghan Mujahideen made them easier to detect. After an IED was exploded, the Afghan Mujahideen often used direct fire weapons such as machine guns and rocket-propelled grenades to continue the attack.

Afghan Mujahideen operating far from the border with Pakistan did not have a ready supply of foreign anti-tank mines. They preferred to make mines from Soviet unexploded ordnance. The anti-tank mines were rarely triggered by pressure fuses. They were almost always remotely detonated.

Common locations for placing these bombs on the ground include animal carcasses, soft drink cans, and boxes. Typically they explode underneath or to the side of the vehicle to cause the maximum amount of damage.

Types

Car Bomb/Vehicle-borne IEDs

Vehicles may be laden with explosives, set to explode by remote control or by a passenger/driver, commonly known as a car bomb or VBIED pronounced vee-bid. On occasion the driver of the car bomb may have been coerced into delivery of the vehicle under duress, a situation known as a Proxy Bomb. Distinguishing markings are low-riding vehicles from excessive weight, vehicles with only one passanger, and where interior of the vehicles look like they have been stripped down and built back up. Car bombs can carry thousands of pounds of explosives and may be augmented with Shipyard Confetti to increase fragmentation. A car bomb is a bomb that is placed in a car or truck and is intended to be exploded while there. ... The Proxy Bomb (also known as a human bomb) was a tactic used by the Provisional IRA for a short time in 1990s, whereby people were forced to drive car bombs into military targets. ... It has been suggested that Fragmentation (weaponry) be merged into this article or section. ...


Suicide bombers

Suicide bombing usually refers to an individual wearing explosives and detonates them in order to kill others including themselves. The bomber will conceal explosive on and around their person, commonly using a vest and will use a timer or some other trigger to detonate the explosives. Suicide bombers in Iraq are common in marketplaces and where Iraqi army and police recruits frequent.


Platter charges

A form of IEDs being used in Iraq are platter charges, which are rectangular or circular pieces of flat metal (usually steel) weighing a few kilograms with plastic explosives pressed onto one side of the platter.[14] The amount of explosive used is usually equal, by weight, to the weight of the platter. The explosives propel the platter into the target with an approximate velocity of 6,000 feet per second (1,829 m/s).[15] The effective range can be as far as 50 meters, limited by the accuracy.


EFPs

Improvised Explosive Device in Iraq. The concave copper shape on top is an explosively formed penetrator.

IEDs have been deployed in the form of Explosively Formed Penetrators, a special type of shaped charge that is effective at long standoffs from the target (50 meters or more). These are especially problematic to counter because they can be placed so far from their intended targets.[16] An EFP is essentially a cylindrical shaped charge with a concave metal disc (often copper) in front, pointed outwards. The force of the shaped charge turns the disc into a bolt of metal, capable of penetrating the armor of most vehicles in Iraq. Image File history File links No higher resolution available. ...

Trigger mechanisms

The British also accused Iran and Hezbollah of teaching Iraqi fighters to use infrared light beams to trigger IEDs. As the occupation forces become more sophisticated in interrupting radio signals around their convoys, the insurgents adapt their triggering methods.[[1]]In some cases, when a more advanced method is disrupted, the insurgents will regress to using uninterruptable means, such as hard lines from the IED to detonator. However, this method is much harder to effectively conceal. It later emerged however, that these advanced IED's were old IRA technology. The infra-red beam method was perfected by the IRA in the early 90's after it acquired the technology from a botched undercover British Army operation. Many of the IED's being used against coalition forces in Iraq were originally developed by the British Army who unintentionally passed the information on to the IRA.

Improvised explosive device - Wikipedia, the free encyclopedia (2001 words)
An improvised explosive device (IED) is the formal name for explosive devices, often used in unconventional warfare or asymmetrical warfare by guerrillas or commando forces in a theater of operations.
An IED typically consists of an explosive charge (potentially assisted by a "booster" charge), a detonator and an initiation system which is a mechanism that initiates the electrical charge that sets off the device.
Mostly the IED's used homemade explosives (HME), although the use of Semtex H smuggled in from Libya in the 1980's was also common in smaller devices.
