BAGHDAD, Oct. 25 -- After 31 months of fighting in Iraq, more than half of all American fatalities are now being caused by powerful roadside bombs that blast fiery, lethal shrapnel into the cabins of armored vehicles, confronting every patrol with an unseen, menacing adversary that is accelerating the U.S. death toll.

U.S. military officials, analysts and militants themselves say insurgents have learned to adapt to U.S. defensive measures by using bigger, more sophisticated and better-concealed bombs known officially as improvised explosive devices, or IEDs. They are sometimes made with multiple artillery shells and Iranian TNT, sometimes disguised as bricks, boosted with rocket propellant, and detonated by a cell phone or a garage door opener.
