Strategy Page describes how the US is beating the IEDs in Iraq.

Intel is discovering the IED-cells and eliminating them. The insurgents are losing skill as time goes on while the US is more proficient at minimizing the threat. More and more routes are secured. The military has contained the insurgency to a few specific regions in Iraq and are making progress at eliminating IEDs in these remaining pockets.

While U.S. infantry and tank units make raids all over central Iraq, the other war, fought largely at night, by engineers and non-infantry troops (often artillerymen) serving as infantry, to catch and stop teams of terrorists trying to set up roadside bombs. The American troops are guided by an intelligence effort that keeps track of IEDs (improvised explosive devices) by type and location. Over 90 percent of IEDs do not do any damage to Americans, or anyone else. Many of these are captured, or at least examined remotely by a robot, before being destroyed. The intel people track changes in IED design, where the are placed and by who, and keep the U.S. troops who hunt the bomb planting teams. The intel crews also use computers and some fancy math to predict where more bombs are likely to be set up. This is based on techniques that go all the way back to World War II, but are much more useful now because of all the cheap computing power available.

One of the mathematical techniques is spatial analysis. Intel analysts mark the location of every IED they find. They find clusters and assign probabilities to IEDs being in a area. IEDs are not laid randomly. Insurgents carrying IEDs can only cover so much distance in a day. This narrows the range where they can plant the bombs. This movement restriction forms the clusters where the IED cell is located.

Alternatively, if intel hears that an IED cell moved into a new town, they can predict a spread of IEDs in the region. They study the production output by quantity and type (1 IED a week, or 2 a week) and probable locations where it can be planted. This helps the engineers and soldiers discover and disarm the IEDs before they harm anyone.

Other intel sources find the locations of the IED cells allowing US forces to specifically target the source of IEDs and halt production in that neighborhood.

US Forces go patrolling at night to clear out IED cells and prevent more bomb planting. Curfews keep civilians indoors. Night Vision gives US soldiers a major advantage. UAVs like the Army Shadows and the AF Predators maintain constant overhead coverage.

New vehicles like the MRAP with V-shaped armored undercarriages are cutting casualties from IEDs. Every little bit helps because IEDs are the last major threat to US troops. And IEDs alone cannot win wars.
