Study: Repeat Iraq Tours Raise Risk of PTSD

Made famous by this picture, the 'Marlboro Marine' was later diagnosed with Post Traumatic Stress Disorder.

U.S. soldiers serving repeated Iraq deployments are 50 percent more likely than those with one tour to suffer from acute combat stress, raising their risk of post-traumatic stress disorder, according to the Army's first survey exploring how today's multiple war-zone rotations affect soldiers' mental health.

More than 650,000 soldiers have deployed to Iraq or Afghanistan since 2001 -- including more than 170,000 now in the Army who have served multiple tours -- so the survey's finding of increased risk from repeated exposure to combat has potentially widespread implications for the all-volunteer force. Earlier Army studies have shown that up to 30 percent of troops deployed to Iraq suffer from depression, anxiety or post-traumatic stress disorder (PTSD), with the latter accounting for about 10 percent.
