Ammunition rigged for an IED discovered by Iraqi police in Baghdad in November 2005

This Cougar in Al Anbar, Iraq, was hit by a directed charge IED approximately 300–500 lbs in size.

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

IEDs may be used in terrorist actions or in unconventional warfare by guerrillas or commando forces in a theater of operations. In the second Iraq War, IEDs were used extensively against coalition forces and by the end of 2007 they had become responsible for approximately 63% of coalition deaths in Iraq.^[1] They are also used in Afghanistan by insurgent groups, and have caused over 66% of the coalition casualties in the 2001–present Afghanistan War.^[2]

IEDs were also used extensively by cadres of the rebel Tamil Tiger (LTTE) organization against military targets in Sri Lanka^[3][4] before the LTTE was dismantled in mid-2009 by the Sri Lankan military forces.

Background[link]

The term Improvised Explosive Device comes from the British Army in the 1970s, after the Provisional Irish Republican Army (IRA) used bombs made from agricultural fertilizer and semtex smuggled from Libya to make highly effective boobytrap devices or remote-controlled bombs. 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 homemade explosives (HME).

An IED has five components: a switch (activator), an initiator (fuse), container (body), charge (explosive), and a power source (battery). An IED designed for use against armored targets such as personnel carriers or tanks will be designed for armour penetration, by using either a shaped charge or an explosively formed penetrator. IEDs are extremely diverse in design, and may contain many types of initiators, detonators, penetrators, and explosive loads. Antipersonnel IEDs typically also contain fragmentation-generating objects such as nails, ball bearings or even small rocks to cause wounds at greater distances than blast-pressure alone could. IEDs are triggered by various methods, including remote control, infra-red or magnetic triggers, pressure-sensitive bars or trip wires (victim-operated). In some cases, multiple IEDs are wired together in a daisy-chain, to attack a convoy of vehicles spread out along a roadway.

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, "own goals," or "self-resolving bomb-tech removal" if the placer is killed in the detonation). Some groups, however, 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.

IEDs may use artillery shells or conventional high-explosive charges as their explosive load as well as homemade explosives. However, the threat exists that toxic chemical, biological, or radioactive (dirty bomb) material may be added to a device, thereby creating other life-threatening effects beyond the shrapnel, concussive blasts and fire normally associated with bombs. Chlorine liquid has been added to IEDs in Iraq, producing clouds of chlorine gas.

A vehicle borne IED, or VBIED, is a military term for a car bomb or truck bomb. These are typically employed by insurgents, 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. The act of a person's being in this vehicle and detonating it is known as an SVBIED suicide.

Of increasing popularity among insurgent forces in Iraq is the HBIED or House Borne IED, coming out of the common military practice of clearing houses, insurgents will rig an entire house to detonate and collapse shortly after a clearing squad has entered.

History[link]

One of the first examples of coordinated large-scale use of IEDs was the Belarussian Rail War launched by Belarussian guerrillas against the Germans during World War II.^[5][6] Both command-detonated and delayed-fuse IEDs were used to derail thousands of German trains during 1943–1944.^[7]

Vietnam[link]

IEDs were used during the Vietnam War by the Viet Cong against land- and river-borne vehicles as well as personnel.^[8] They were commonly constructed using materials from unexploded American ordnance.^[9] Thirty-three percent of U.S. casualties in Vietnam and twenty-eight percent of deaths were officially attributed to mines; these figures include losses caused by both IEDs and commercially manufactured mines.^[10]

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 string was stretched across a path or doorway opening and firmly tied down. In alternative fashion, 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.

The rubber band grenade was another booby trap. To make this device, a Viet Cong guerrilla 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 rubber band would be eaten away by the chemical action of the fuel, releasing the safety lever and detonating the grenade.

Another 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 jar and the grenade would detonate. This particular variant was popular with helicopter warfare, and were used 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.

Northern Ireland[link]

Throughout The Troubles, the Provisional IRA made extensive use of IEDs in their 1969-1997 campaign. They used barrack buster mortars and remote controlled IEDs. Members of the PIRA developed and counter-developed devices and tactics. PIRA bombs became highly sophisticated, featuring anti-handling devices such as a mercury tilt switch or microswitches. These devices would detonate the bomb if it was moved in any way. Typically, the safety-arming device used was a clockwork Memopark timer, which armed the bomb five minutes after it was placed by completing an electrical circuit supplying power to the anti-handling device. Depending on the particular design (e.g., boobytrapped briefcase or car bomb) an independent electrical circuit supplied power to a conventional timer set for the intended time delay, e.g. 40 minutes. However, some electronic delays developed by PIRA technicians could be set to accurately detonate a bomb weeks after it was hidden, which is what happened in the Brighton hotel bomb attack of 1984. Initially, bombs were detonated either by timer or by simple command wire. Later, bombs could be detonated by radio control. Initially, simple servos from radio-controlled aircraft were used to close the electrical circuit and supply power to the detonator. After the British developed jammers, PIRA technicians introduced devices that required a sequence of pulsed radio codes to arm and detonate them. These were harder to jam.

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. 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.

Most IEDs used commercial or homemade explosives, although the use of Semtex-H smuggled in from Libya in the 1980s was also common from the mid-1980s onward. Bomb Disposal teams from 321 EOD manned by Ammunition Technicians were deployed in those areas to deal with the IED threat.

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 review recommended bringing in psychometric testing of soldiers to ensure those chosen had the correct mental preparation for high risk bomb disposal duties.

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 (now privatised into QinetiQ), 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.

The bomb disposal operations were led by Ammunition Technicians and Ammunition Technical Officers from 321 EOD, and were trained at the Felix Centre at the Army School of Ammunition.

Afghanistan[link]

U.S. Marines with Explosive Ordnance Disposal (EOD) destroy an Improvised Explosive Device (IED) cache in southern Afghanistan in June 2010.

Starting six months before the invasion of Afghanistan by the USSR on 27 December 1979, the Afghan Mujahideen were supplied with large quantities of military supplies from the United States. Among those supplies were many types of anti-tank mines. The insurgents often removed the explosives from several foreign anti-tank mines, and combined the explosives in tin cooking-oil cans for a more powerful blast. By combining the explosives from several mines and placing them in tin cans, the insurgents made them more powerful, but sometimes also easier to detect by Soviet sappers using mine detectors. After an IED was detonated, the insurgents often used direct-fire weapons such as machine guns and rocket-propelled grenades to continue the attack.

Afghan insurgents operating far from the border with Pakistan did not have a ready supply of foreign anti-tank mines. They preferred to make IEDs from Soviet unexploded ordnance. The devices were rarely triggered by pressure fuses. They were almost always remotely detonated. Since the 2001 invasion of Afghanistan, the Taliban and its supporters have used IEDs against NATO and Afghan military and civilian vehicles. This has become the most common method of attack against NATO forces, with IED attacks increasing consistently year on year.

In January 2010, it was reported by military experts that Taliban fighters had developed a new generation IED, that would be almost undetectable, because it had no metal or electronic parts. The expertise for this new generation came likely from foreign fighters and the devices were being mass produced in India on an industrial level and supplied in Afghanistan through the Indian Consulates in Afghanistan. Before this new development, IEDs would be mostly triggered by two hacksaw blades separated using a spacer. Stepping on or driving over these blades would close an electronic circuit that so detonated the explosive – often an artillery shell.

In the new model, these metal saw blades have been replaced with graphite blades and the artillery shells with ammonium nitrate. The damage then is caused by the power of the blast rather than by metal fragments, or shrapnel.

According to a report by Homeland Security Market Research in the USA, the number of IEDs used in Afghanistan had increased by 400 percent since 2007 and the number of troops killed by them by 400 percent, and those wounded by 700 percent. It has been reported that IEDs are the number one cause of death among NATO troops in Afghanistan.^[11]

A brigade commander said that sniffer dogs are the most reliable way of detecting IEDs.^[12] However, statistical evidence gathered by the US Army Maneuver Support Center at Fort Leonard Wood, MO shows that the dogs are not the most effective means of detecting IEDs.^{[citation needed]}

Lebanon[link]

Hezbollah made extensive use of IEDs to attack Israeli forces after Israel's 1982 invasion of Lebanon. Israel withdrew from most of Lebanon in 1985 but still kept troops stationed in a buffer zone in southern Lebanon. Hezbollah frequently used IEDs to attack Israeli vehicles in this area up until the Israeli withdrawal in May 2000.

One such bomb killed Israeli Brigadier General Erez Gerstein^[13] on February 28, 1999, the highest-ranking Israeli to die in Lebanon since Yekutiel Adam's death in 1982.

Also in the 2006 Israel-Lebanon conflict, a Merkava Mark II tank was hit by a pre-positioned Hezbollah IED, killing all 4 IDF servicemen on board,^[14] the first of two IEDs to damage a Merkava tank.

Chechnya[link]

IEDs have also been popular in Chechnya, where Russian forces were engaged in fighting with rebel elements. While no concrete statistics are available on this matter, bombs have accounted for many Russian deaths in both the First Chechen War (1994–1996) and the Second (1999–2008).

Iraq[link]

Controlled explosion of IED, US Army in Iraq

In the 2003–2011 Iraq War, IEDs have been used extensively against coalition forces and by the end of 2007 they have been responsible for at least 64% of coalition deaths in Iraq.^[1]

Beginning in July 2003, the Iraqi insurgency used IEDs to target coalition vehicles. According to iCasualties.org, as of April 21, 2011 at least (missing data)% of Coalition fatalities in the Iraq War are caused by IEDs.^[1] According to the Washington Post, 64% of U.S deaths in Iraq occurred due to IEDs.^[15] A French study^[16] showed that in Iraq, from March 2003 to November 2006, on a global 3,070 deaths in the US-led Coalition soldiers, 1,257 were caused by IEDs, i.e. 41%. That is to say more than in the "normal fights" (1027 dead, 34%). Insurgents now use the bombs to target not only Coalition vehicles but Iraqi police and civilian transportation as well.

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; however, as vehicle armor was improved on military vehicles, insurgents began placing IEDs in elevated positions such as on road signs, utility poles, or trees, in order to hit less protected areas.

IEDs in Iraq may be made with artillery or mortar shells or with varying amounts of bulk or homemade explosives. Early during the Iraq war, the bulk explosives were often obtained from stored munitions bunkers to include stripping landmines of their explosives.

Despite the increased armor, IEDs have been killing military personnel and civilians with greater frequency. May 2007 was the deadliest month for IED attacks thus far, with a reported 89 of the 129 Coalition casualties coming from an IED attack.^[1] According to the Pentagon, 250,000 tons (of 650,000 tons total) of Iraqi ordnance were looted, providing a large supply of ammunition for the insurgents.

In October 2005, the UK government charged that Iran was supplying insurgents with the technological know-how to make shaped charge IEDs.^[17] Both Iranian and Iraqi government officials denied the allegations.^[18][19]

United States[link]

In the 1995 Oklahoma City bombing, Timothy McVeigh and Terry Nichols built an IED with ammonium nitrate fertilizer, nitromethane and stolen commercial explosives in a rental truck. McVeigh detonated it next to the Alfred P. Murrah Federal Building, killing 168 people, 19 of whom were children.

In January 2011, a shaped pipe bomb was discovered and defused at a Martin Luther King Jr. memorial march in Spokane, Washington. The FBI said that the bomb was specifically designed to cause maximum harm as the explosive device was, according to the Los Angeles Times, packed with fishing weights covered in rat poison, and may have been racially motivated. No one was injured during the event.^{[citation needed]}

India[link]

IEDs are increasingly being used by Maoists in India.^[20]

On 13 July 2011, three IEDs were used by the Indian Mujahideen terrorist group to carry out a coordinated attack on the city of Mumbai, killing 19 people and injuring 130 more.^[21][22]

Nepal[link]

IEDs were also widely used in the 10-years long civil war of the Maoists in Nepal, ranging from those bought from illicit groups in India and China, to self-made devices. Typically used devices were pressure-cooker bombs, socket bombs, pipe bombs, bucket bombs, etc. The devices were used more for the act of terrorizing the urban population rather than for fatal causes, placed in front of governmental offices, street corners or road sides. Mainly, the home-made IEDs were responsible for destruction of majority of structures targeted by the Maoists and assisted greatly in spreading terror among the public.

Syria[link]

During the Syrian uprising militant insurgents were using IEDs to attack buses, trucks and tanks.^[23]

Types of devices[link]

By warhead[link]

The Dictionary of Military and Associated Terms (JCS Pub 1-02) includes two definitions for improvised devices: improvised explosive devices (IED) and improvised nuclear device (IND).^[24] These definitions address the Nuclear and Explosive in CBRNE. That leaves chemical, biological and radiological undefined. Four definitions have been created to build on the structure of the JCS definition. Terms have been created to standardize the language of first responders and members of the military and to correlate the operational picture.^[25]

Explosive

A device placed or fabricated in an improvised manner incorporating destructive, lethal, noxious, pyrotechnic, or incendiary chemicals and designed to destroy, incapacitate, harass, or distract. It may incorporate military stores, but is normally devised from non-military components.

Nuclear

A device incorporating radioactive materials designed to result in the dispersal of radioactive material (a dirty bomb) or in the formation of nuclear-yield reaction. Such devices may be fabricated in a completely improvised manner or may be an improvised modification to a nuclear weapon.

Chemical

A device incorporating the toxic attributes of chemical materials designed to result in the dispersal of these toxic chemical materials for the purpose of creating a primary patho-physiological toxic effect (morbidity and mortality), or secondary psychological effect (causing fear and behavior modification) on a larger population. Such devices may be fabricated in a completely improvised manner or may be an improvised modification to an existing weapon.

Biological

A device incorporating biological materials designed to result in the dispersal of vector borne biological material for the purpose of creating a primary patho-physiological toxic effect (morbidity and mortality), or secondary psychological effect (causing fear and behavior modification) on a larger population. Such devices are fabricated in a completely improvised manner.

Radioactive

A device incorporating radioactive materials designed to result in the dispersal of radioactive material for the purpose of area denial and economic damage, and/or for the purpose of creating a primary patho-physiological toxic effect (morbidity and mortality), or secondary psychological effect (causing fear and behavior modification) on a larger population. Such devices may be fabricated in a completely improvised manner or may be an improvised modification to an existing nuclear weapon. Also called a Radiological Dispersion Device (RDD) or "dirty bomb".

Incendiary

A device making use of exothermic chemical reactions designed to result in the rapid spread of fire for the purpose of creating a primary patho-physiological effect (morbidity and mortality), or secondary psychological effect (causing fear and behavior modification) on a larger population or it may be used with the intent of gaining a tactical advantage. Such devices may be fabricated in a completely improvised manner or may be an improvised modification to an existing weapon. A common type of this is the molotov cocktail.

By delivery mechanism[link]

Car[link]

Artillery shells and gasoline cans discovered in the back of a pick-up truck in Iraq

Vehicles may be laden with explosives, set to explode by remote control or by a passenger/driver, commonly known as a car bomb or vehicle-based IED (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 features are low-riding vehicles with excessive weight, vehicles with only one passenger, and ones where the interior of the vehicles look as if they have been stripped down and built back up. Car bombs can carry thousands of pounds of explosives and may be augmented with shrapnel to increase fragmentation. The U.S. State Department has published a guide on car bomb awareness.^[26]

Boat[link]

Boats laden with explosives can be used against ships and areas connected to water. An early example of this type was the Japanese Shinyo suicide boats during World War II. The boats were laden with explosives and attempted to ram Allied ships, sometimes successfully, having sunk or severely damaged several American ships by war's end. Suicide bombers used a boat-borne IED to attack the USS Cole, US and UK troops have also been killed by boat-borne IEDs in Iraq.^[16][27]

Animal[link]

Monkeys and war pigs were used as incendiaries around 1000 AD. More famously the "anti-tank dog" and "bat bomb" were developed during WW2. In recent times, a two-year old child and seven other people were killed by explosives strapped to a horse in the town of Chita in Colombia^[28] The carcasses of certain animals were also used to conceal explosive devices by the Iraqi insurgency.^[29]

Collar[link]

IEDs strapped to the necks of farmers have been used on at least three occasions by guerrillas in Colombia, as a way of extortion.^[30][31] American pizza delivery man Brian Douglas Wells was killed in 2003 by an explosive fastened to his neck, purportedly under duress from the maker of the bomb.^[32] In 2011 a schoolgirl in Sydney, Australia had a suspected collar bomb attached to her by an attacker in her home. The device was removed by police after a ten-hour operation and proved to be a hoax.^[33]

Suicide[link]

Suicide bombing usually refers to an individual wearing explosives and detonating them in order to kill others including themselves, a technique pioneered by LTTE (Tamil Tigers).^[34] The bomber will conceal explosives on and around their person, commonly using a vest and will use a timer or some other trigger to detonate the explosives. The logic behind such attacks is the belief that an IED delivered by a human has a greater chance of achieving success than any other method of attack. In addition, there is the psychological impact of terrorists prepared to deliberately sacrifice themselves for their cause.^[35]

Platter charge[link]

This propels the platter into the target with an approximate velocity of 6,000 feet per second (1,800 m/s).^[36] The effective range can be as far as 50 meters, limited by the accuracy.

Explosively formed penetrators[link]

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 far from their intended targets.^[37] An EFP is essentially a cylindrical shaped charge with a concave metal disc (often copper) in front, pointed inward. The force of the shaped charge turns the disc into a high velocity slug, capable of penetrating the armor of most vehicles in Iraq.

Rocket[link]

In 2008, rocket-propelled IEDs, dubbed Improvised Rocket Assisted Mortars (IRAM) by the military, came to be employed in numbers against U.S. forces in Iraq. They have been described as propane tanks packed with explosives and powered by 107 mm rockets.^[38] They are similar to some Provisional IRA barrack buster mortars.

By trigger mechanisms[link]

Wire

Command wire-improvised explosive devices (CWIED) use an electrical firing cable that affords the user complete control over the device right up until the moment of initiation.^[35]

Radio

The trigger for a radio-controlled improvised explosive device (RCIED) is controlled by radio link. The device is constructed so that the receiver is connected to an electrical firing circuit and the transmitter operated by the perpetrator at a distance, A signal from the transmitter causes the receiver to trigger a firing pulse that operates the switch. Usually the switch fires an initiator; however, the output may also be used to remotely arm an explosive circuit. Often the transmitter and receiver operate on a matched coding system that prevents the RCIED from being initiated by spurious radio frequency signals.^[35] An RCIED can be triggered from any number of different mechanisms including car alarms, wireless door bells, cell phones, pagers and encrypted GMRS radios.^[35]

Cell phone

A radio-controlled IED (RCIED) incorporating a cell phone that is modified and connected to an electrical firing circuit. Cell phones operate in the UHF band in line of sight with base transceiver station (BTS) antennae sites. In the common scenario, receipt of a paging signal by phone is sufficient to initiate the IED firing circuit.^[35]

Victim-operated

Victim-operated improvised explosive devices (VOIED) are designed to function upon contact with a victim; also known as booby traps. VOIED switches are often well hidden from the victim or disguised as innocuous everyday objects. They are operated by means of movement. Switching methods include tripwire, pressure mats, spring-loaded release, push, pull or tilt. Common forms of VOIED include the under-vehicle IED (UVIED) and improvised landmines.^[35]

Infrared[link]

The British accused Iran and Hezbollah of teaching Iraqi fighters to use infrared light beams to trigger IEDs. As the occupation forces became more sophisticated in interrupting radio signals around their convoys, the insurgents adapted their triggering methods.^[39] In some cases, when a more advanced method was disrupted, the insurgents regressed to using interruptible means, such as hard wires from the IED to detonator; however, this method is much harder to effectively conceal. It later emerged however, that these so-called "advanced" IEDs were actually old IRA technology. The infrared beam method was perfected by the IRA in the early '90s after it acquired the technology from a botched undercover British Army operation. Many of the IEDs being used against coalition forces in Iraq were originally developed by the British Army who unintentionally passed the information on to the IRA.^[40] The IRA taught their techniques to the Palestine Liberation Organisation and the knowledge spread to Iraq.^[41]

Surgically implanted[link]

In May 2012 American counter-terrorism officials leaked their acquisition of documents describing the preparation and use of surgically implanted improvised explosive devices.^[42][43][44] The devices were designed to evade detection. The devices were described as containing no metal, so they could not be detected by xrays.

Security officials referred to bombs being surgically implanted into suicide bomber's "love handles".^[42] In August 2009 Abdullah al-Asiri, the younger brother of Ibrahim al-Asiri, Al Qaeda in the Arabian Peninsula's chief bomb-maker tried to assassinate a Saudi prince with bomb inserted up his anus. That effort was a failure, inflicting relatively slight wounds on the prince.

According to The Daily Mirror UK security officials at MI-6 asserted that female bombers could travel undetected carrying the explosive chemicals in otherwise standard breast implants.^[45]

The bomber would blow up the implanted explosives by injecting a chemical trigger.^[44]

Detection and disarmament[link]

Since these devices are improvised, there are no specific guidelines for explosive ordnance disposal (EOD) personnel to use to positively identify or categorize them.^{[dubious – discuss]} 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.

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 supposed effectiveness of IED jamming systems, including vehicle- and personally-mounted systems, has caused IED technology to essentially regress to command-wire detonation methods.^[46] 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 are more readily detected.

Military forces from India, 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. From the research and development side, programs such as the new Canadian Unmanned Systems Challenge, will bring students groups together to invent an unmanned device to both locate IEDs and pinpoint the insurgents.^[47]

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.

There are many people in history who are commonly appended with the phrase "the Great", or who were called that or an equivalent phrase in their own language. Other languages have their own suffixes such as e Bozorg and e azam in Persian and Urdu respectively.

In Persia, the title "the Great" at first seems to be a colloquial version of the Old Persian title "Great King". This title was first used by the conqueror Cyrus II of Persia.^[1]

The Persian title was inherited by Alexander III of Macedon (336–323 BC) when he conquered the Persian Empire, and the epithet "Great" eventually became personally associated with him. The first reference (in a comedy by Plautus)^[2] assumes that everyone knew who "Alexander the Great" was; however, there is no earlier evidence that Alexander III of Macedon was called "the Great".

The early Seleucid kings, who succeeded Alexander in Persia, used "Great King" in local documents, but the title was most notably used for Antiochus the Great (223–187 BC).

Later rulers and commanders began to use the epithet "the Great" as a personal name, like the Roman general Pompey. Others received the surname retrospectively, like the Carthaginian Hanno and the Indian emperor Ashoka the Great. Once the surname gained currency, it was also used as an honorific surname for people without political careers, like the philosopher Albert the Great.

As there are no objective criteria for "greatness", the persistence of later generations in using the designation greatly varies. For example, Louis XIV of France was often referred to as "The Great" in his lifetime but is rarely called such nowadays, while Frederick II of Prussia is still called "The Great". A later Hohenzollern - Wilhelm I - was often called "The Great" in the time of his grandson Wilhelm II, but rarely later.
