What is a primary component of an IED?

A primary component of an improvised explosive device (IED) is the explosive charge, which can be made from various materials such as commercial explosives, military ordnance, or homemade mixtures. Additionally, IEDs often include a triggering mechanism, such as a timer or remote control, and a casing to contain the explosion and direct shrapnel. The combination of these elements allows for the creation of a device that can cause significant damage and casualties.
