Define “secondary device” in the context of IEDs.

In the context of improvised explosive devices (IEDs), a "secondary device" refers specifically to an explosive device that is engineered to detonate after an initial explosion. This tactic is often employed to target responders and bystanders who may rush to the scene of the first explosion, thereby increasing casualties and chaos. The design of a secondary device takes advantage of the immediate aftermath of the first blast, exploiting the potential vulnerability of individuals who are drawn in by the explosion or are attempting to provide assistance.

This strategic use of a secondary device highlights the importance of situational awareness and caution in potential explosive scenarios, as responders need to be vigilant for further threats. Understanding the role and function of secondary devices is crucial in countering IED threats effectively.
