Improvised explosive device InformationAn 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 64% of coalition deaths in Iraq. They are also used in Afghanistan by insurgent groups, and have caused over 66% of the coalition casualties in the 2001–present Afghanistan War.
They were also used extensively by cadres of the rebel Tamil Tiger (LTTE) organization against military targets in Sri Lanka before the LTTE was dismantled in mid 2009 by the Sri Lankan military forces.
