By the end of August the total number of suicidal deaths this year in the war is 93 while 31 are still being investigated. If this trend continues, it will exceed for the first time since Vietnam and will be even higher than last year’s total. The USMC, which is the second largest force in Iraq and consists mostly of younger men, had a suicidal rate of 16.5 per 100,000 people in 2007. The Air Force and Navy had rates of a little over 10 per 100,000 people.
