...if they're not committing suicide.

The Guardian, via Salon:

Up to one in five of the American military personnel in Iraq will suffer from post-traumatic stress disorder, say senior forces' medical staff dealing with the psychiatric fallout of the war.

This revelation follows the disclosure last month that more than 600 US servicemen and women have been evacuated from the country for psychiatric reasons since the conflict started last March.

At least 22 US soldiers have killed themselves - a rate considered abnormally high - mostly since President George Bush declared an end to major combat on 1 May last year, These suicides have led to a high-level Department of Defence investigation, details of which will be disclosed in the next few weeks.
