I really enjoy the Hero Workouts in CrossFit. Every time I read who they are dedicated to it seems that they are always killed by an IED. What is that?

An Improvised Explosive Device (IED) is an explosive device made from ordinary materials that can be found around the home and constructed without prior knowledge or permission of the relevant authority. It is often initiated remotely, but can also be activated by timers, pressure plates, or other sensors. IEDs have been used in combat since the 19th century but have become increasingly more sophisticated with the modern day.
