Which of the following are main components of an IED?

The main components of an improvised explosive device (IED) typically include a firing system, power source, detonation cord (det cord), and a main charge. The firing system is crucial as it initiates the explosive reaction. This could be done through a variety of triggering mechanisms, including manual or electronic methods. The power source, which could be batteries or other energy sources, provides the necessary energy to the firing system to trigger the explosion. Det cord is often used to efficiently transfer the explosive signal from the initiation point to the main charge, ensuring a synchronized detonation.

The main charge refers to the bulk explosive material that produces the intended destructive effect when detonated. Understanding these fundamental components is essential for identifying and neutralizing IEDs, making these elements critical in CIED training and operations.
