improvised explosive device

An improvised explosive device (IED) 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.IEDs may be used in terrorist actions or in unconventional warfare by guerrillas or commando forces in a theater of operations. In the 2003–present  Iraq War, IEDs have been used extensively against coalition forces and by the end of 2007 they have been the reason for two-thirds of all US deaths in Iraq. They are also used extensively by cadres of the rebel Tamil Tiger (LTTE) organization against military and civilian targets in Sri Lanka.
