An IED is an improvised explosive device, meaning a homemade bomb that is built and used outside normal military manufacturing and deployment methods.

Basic definition

  • An IED is a bomb constructed in an improvised way, often from a mix of military and non‑military components such as artillery shells, commercial explosives, or homemade explosives.
  • It is designed to kill, injure, or damage people, vehicles, or buildings, and is commonly used as a weapon by terrorists, insurgents, and other non‑state armed groups.

How an IED works

  • Most IEDs include four main parts: an initiating mechanism (trigger), a detonator, an explosive charge, and a casing or added fragments like nails or ball bearings to increase harm.
  • Triggers can range from simple pressure plates or tripwires to remote controls, timers, or adapted electronic devices like mobile phones, allowing detonation from a distance.

Common forms and use

  • IEDs are often used as roadside bombs, hidden along routes to hit vehicles or patrols, but they can also be placed in buildings, bags, or vehicles (car or truck bombs).
  • They play a major role in modern low‑intensity conflicts, where they are used to ambush, intimidate, or disrupt regular military forces and civilian life.

Safety note

  • If someone ever suspects an explosive device, standard guidance is to stay away, avoid using radios or phones near it, and contact local authorities or emergency services immediately rather than trying to inspect it.
