The military has confirmed it is investigating 7 soldier suicides that have occurred between the period of one week before the Iraq war began in March through the present time. All were deployed for the war. Five were in the army and one or two were in the Marines.

...the Army and the Marines have stressed suicide prevention in the past year after increases in suicides that may have been at least partially attributable to lengthy deployments and other strains following the Sept. 11, 2001, terrorist attacks on New York and Washington and the ensuing war in Afghanistan.

Overall, the military has not released an official count of possible suicides under investigation, and the total could be higher than seven, given a number of unexplained deaths included in the Pentagon's casualty statistics. The military has reported nine cases of accidental death that could include suicides, most of which were from "noncombat weapons discharges." In 12 other cases, the cause of death has been officially listed as "other" and described only as "noncombat injuries."
