An IED is described by the acronym SIMPICE. Which components are included?

• A. IMP: Initiator, Main Charge, Power.
• B. IED stands for Immediate Electronic Device.
• C. SIMPLE: Switch, Initiator, Main Charge, Energy.
• D. SIMPICE: Switch, Initiator, Main Charge, Power, Container, Enhancements.

Answer: (D)

Understanding how IEDs are described in field training comes from recognizing six functional pieces that cover how the device is triggered, what actually causes the blast, and how it’s held together. SIMPICE is this six-part framework: Switch, Initiator, Main Charge, Power, Container, Enhancements. The Switch is the triggering mechanism the user interacts with. The Initiator is the element that starts the sequence once the switch is engaged. The Main Charge is the primary explosive payload designed to produce the desired effect. Power refers to the energy source that powers the initiation and timing, such as a battery or capacitor. Container is the housing that holds all components and can influence concealment and blast characteristics. Enhancements are additional features added to improve reliability, timing accuracy, or lethality, like timing devices or boosters. This set of components best matches the standard way practitioners describe an IED, whereas other options change or omit elements, or use terms that don’t align with the common framework.
