The Toll

The cost in Iraq has been disproportionally shouldered by those who should not even be there: the National Guard and the Reservists.

The National Guard and Reserves are suffering a strikingly higher share of U.S. casualties in Iraq, their portion of total American military deaths nearly doubling since last year.

Reservists have accounted for one-quarter of all U.S. deaths since the Iraq war began, but the proportion has grown over time. It was 10 percent for the five weeks it took to topple Baghdad in the spring of 2003, and 20 percent for 2004 as a whole.

The trend accelerated this year. For the first nine months of 2005 reservists accounted for 36 percent of U.S. deaths, and for August and September it was 56 percent, according to Pentagon figures.
