The components included in SIMPCE for an IED are which of the following?

• A. Sensors, Initiator, Main Charge, Power, Container, Enhancements
• B. Switch, Initiator, Main Charge, Power, Container, Enhancements
• C. Switch, Initiator, Main Charge, Power, Container, Electronics
• D. Switch, Initiator, Main Charge, Power, Capsule, Enhancements

Answer: (B)

SIMPCE is a mnemonic used to identify the six functional parts that makeup an IED: Switch, Initiator, Main Charge, Power, Container, and Enhancements. Each part has a specific role in how the device operates, which is why this six-category grouping is used in training and investigation. The Switch represents the actuation method—the trigger that starts the sequence. The Initiator is the component that starts the firing train once the switch is activated. The Main Charge is the explosive mass intended to produce the desired effect. The Power provides the energy needed to run the circuit, including any timing or sequencing elements. The Container is the housing, which not only holds everything together but can influence concealment, protection, and dispersion. Enhancements cover any additional features that modify the device’s performance, such as boosters, delays, or other accessories that affect reliability or timing. This set is the standard way to categorize IEDs in EOD and investigative contexts because it consistently covers actuation, initiation, energetic content, energy source, enclosure, and optional features—without mixing in terms like Sensors, Electronics, or Capsule, which aren’t part of the SIMPCE framework.
