By far, motor vehicle accidents are the most prevalent, claiming 46 American lives. One of those soldiers was run over by a tank while he was sleeping, three perished when their truck fell into a ravine, one died when a Bradley Fighting Vehicle plunged over a cliff and at least seven were killed in vehicle rollovers.
Next most common were accidents involving explosives and weapons, which have caused 27 fatalities. Those included a soldier killed when a ricocheting bullet at a small-arms training range in Iraq triggered a fire, another who died when his rifle discharged as he was putting it away and two killed when a munitions bunker caught fire and exploded.
Warplane or helicopter accidents account for 23 deaths, virtually all of which happened during the intense combat phase of the war, even though many of the mishaps did not occur in battle. That marks an improvement over the aviation toll in the first Persian Gulf War in 1990-91, when at least 38 died that way.
At least seven troops have drowned in canals or rivers. One was electrocuted. And at least another eight have perished in "friendly fire" incidents, such as the April 2 accidental downing of a Navy FA-18C fighter by a U.S. Patriot missile, and the death two weeks later of a Marine corporal shot by American gunners who mistook him for an enemy soldier.

And the military is bracing for even more accidental deaths when troops now in Iraq come home. Off-duty mishaps usually increase among newly returned troops who can be accident-prone because of fatigue or too much celebrating.
