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 HME lab refers to a Homemade Explosive Lab, or the physical location where the devices are crafted.
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 armoured targets such as personnel carriers or tanks will be designed for armour penetration, by using a

By warhead
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). 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.
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.

that is effective at long standoffs from the target (50 meters or more), however they are not accurate at long distances. This is because of how they are produced. The large "slug" projected from the explosion has no stabilization because it has no tail fins and it does not spin like a bullet from a rifle. Without this stabilization the trajectory can not be accurately determined beyond 50 meters. An EFP is essentially a cylindrical shaped charge with a machined 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.
Directionally focused charges
Directionally focused charges (also known as directionally focused fragmentary charges depending on the construction) are very similar to EFPs, with the main difference being that the top plate is usually flat and not concave. It also is not made with machined copper but much cheaper cast or cut metal. When made for fragmentation, the contents of the charge are usually nuts, bolts, ball bearings and other similar shrapnel products and explosive. If it only consists of the flat metal plate, it is known as a platter charge, serving a similar role as an EFP with reduced effect but easier construction.

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 or jamming. An RCIED can be triggered from any number of different radio-frequency based mechanisms including handheld remote control transmitters, car alarms, wireless door bells, cell phones, pager

In some cases, when a more advanced method was disrupted, the insurgents regressed to using uninterruptible 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 "advanced" IEDs were actually old IRA technology.

Counterefforts
Counter-IED efforts are done primarily by military, law enforcement, diplomatic, financial, and intelligence communities and involve a comprehensive approach to countering the threat networks that employ IEDs, not just efforts to defeat the devices themselves.
Detection and disarmament
Because the components of these devices are being used in a manner not intended by their manufacturer, and because the method of producing the explosion is limited only by the science and imagination of the perpetrator, it is not possible to follow a step-by-step guide to detect and disarm a device that an individual has only recently developed. As such, explosive ordnance disposal (IEDD) operators must be able to fall back on their extensive knowledge of the first principles of explosives

) 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 and law enforcement personnel from around the world have developed a number of render-safe procedures (RSPs) 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. 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 and law enforcement 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 student groups together to invent an unmanned device to both locate IEDs and pinpoint the insurgents.

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 Vietnam

ese 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. They could also be partially filled with gasoline or jellied gasoline, Napalm
