<|assistant|>
IEDs (Improvised Explosive Devices) are devices constructed and designed to cause destruction, usually made from commonly available materials such as powder kegs, grenades, and pipe bombs. They can be initiated either by a timed mechanisms or upon physical contact. Explosive materials are often combined with other substances such as nails, screws and ball bearings to increase the fragmentation potential of an IED, and they are often packed with plastic explosives such as PETN or TNT. IEDs have been widely used by armed groups and insurgents, and are often hidden and planted in order to harm troops or civilians.
