What is with the euphemism IED?

In this Wiki page for the movie the Hurt Locker Jeremy Renner lifts up a wire that is attached to half a dozen tank bombs. It’s a pretty good example of an Improvised Explosive Device.

“IED” is fine. We’ll be in euphemism territory when they start calling them “ferric precipitation modules”.

What a terrific comment. I am anxious to hear more.
