Which of the following is NOT one of the five parts of an IED?

The five parts of an improvised explosive device (IED) are crucial for understanding how these devices are constructed and how they function. The components typically include:

1. Main Charge: This is the explosive material that causes the explosion when detonated.

2. Container: This is the casing or the body that holds the main charge and often helps focus the blast.

3. Initiation: This refers to the triggering mechanism that activates the device, such as a fuse or detonation cord.

4. Power Source: This component is necessary to provide energy to the initiation system, which can include batteries or other means of generating a signal or power to detonate.

Since the question is asking for a part that is NOT included in the five essential components, identifying "Container" as the correct answer acknowledges that it is actually one of the critical components. The other choices—Main charge, Initiation, and Power source—are integral parts of the IED system, establishing that the container is inherently part of the device’s structure rather than being excluded from the core assembly. Thus, it highlights the importance of understanding each component's role in the overall functionality of an IED.
