The unreported cost of war: at least 827 American wounded

US military casualties from the occupation of Iraq have been more than twice the number most Americans have been led to believe because of an extraordinarily high number of accidents, suicides and other non-combat deaths in the ranks that have gone largely unreported in the media.

Unofficial figures are in the thousands. About half have been injured since the president's triumphant appearance on board the aircraft carrier USS Lincoln at the beginning of May. Many of the wounded have lost limbs.

The figures are politically sensitive. The number of American combat deaths since the start of the war is 166 - 19 more than the death toll in the first Gulf war.

The passing of that benchmark last month erased the perception, popular at the time Baghdad fell, that the US had scored an easy victory.

The Pentagon figure for "wounded in action" in Iraq is 827, but here again the total number of injuries appears to be much higher.

The estimate given by central command in Qatar is 926, but according to Lieutenant-Colonel Allen DeLane, who is in charge of the airlift of the wounded into Andrews air base, that too is understated.

"Since the war has started, I can't give you an exact number because that's classified information, but I can say to you over 4,000 have stayed here at Andrews, and that number doubles when you count the people that come here to Andrews and then we send them to other places like Walter Reed and Bethesda, which are in this area also," Col DeLane told National Public Radio.
