IEDs and the Navy?

According to Bill Gertz and Rowan Scarborough here:

According to military officials in Baghdad, the terrorists are using at least three types of triggers for IEDs, including infrared-signaled garage-door openers, infrared automobile car-lock openers and hard-wired bombs. All are set off when vehicles move through a target area.
To counter the threat, the military has been using broadband radio-signal jammers. But the jammers create other problems; namely, they also disrupt communications used by military forces.
Navy Capt. Chris Field, commander of the Pacific Fleet's electronic attack wing, said in a speech Oct. 24 that EA-6B Prowler electronic warfare jets are being used in Iraq to disrupt IED signals, along with other terrorist communications.

As the column points out, some better ways to deal with IED threat need to be found. The success the terrorists are having with them in Iraq is spreading (of course, it aids the terrorists in Iraq that there seems to be a virtually infinite supply of mortar and artillery rounds from which to construct the bombs).
