Identity Enabled Devices

ABC News anchor Bob Woodruff and his cameraman Doug Vogt were injured in Iraq by an IED (Improvised Explosive Device).

Two thoughts:

1. As opposed to naturally occuring explosive devices? Presumably the distinction is between explosive devices created by recognized arms manufacturers and those cobbled together with duct tape and spit. Given the obviously lethal nature of any such ad hoc devices, is the distinction relevant? Do convoy drivers say to themselves as they drive through hot spots 'Phew, only need to worry about brand name bombs today'?
   
2. The military must be the only community more inclined to create unnecessary acronyms than IT.
