In a 7 January 2004 report on “All Things Considered” (NPR), Daniel Zwerdling reported on the number of US casualties in Iraq apart from those killed. (As of 17 January 2004 the number killed was 501.)

Zwerdling’s efforts to find out how many soldiers who have been seriously enough injured or ill to be evacuated from Iraq were substantial—the military is not forthcoming.
As of early January, Zwerdling was able to get a number of casualties only from the Army. The number of American soldiers who have become seriously sick and injured in Iraq was 8, 848! That’s amazing!
