An Improvised Explosive Device, also called an IED, is a street-made weapon. These are the uglies blowing up civilians and soldiers in Iraq.
This photo of one IED found in Iraq was submitted to Shock and Awe section of the US soldier bulletin board Military.com by Shain Chmura. He adds: Make special note of the "01 Call Missed" displayed on the phone.
I don't know anything about this device. The image is courtesy of the US Department of Defense.
