What are the primary components of an Improvised Explosive Device (IED)?

The primary components of an Improvised Explosive Device (IED) are indeed best represented by the choice that includes the power source, initiator, explosive, and switch.

The power source is critical as it provides the necessary energy to activate the device. The initiator is responsible for starting the explosive reaction; this component is usually sensitive enough to trigger an explosion upon activation. The explosive itself is the main charge that generates the destructive force. Finally, the switch is the mechanism that controls the initiation of the explosive, allowing the user to set off the device at a chosen moment.

Understanding these components is essential for recognizing how IEDs function and can help in developing countermeasures to detect or mitigate such threats in various operational environments.
