Training on vet suicides set at Nevada prisons

Four months after he enlisted in the Army at 18, John Morse IV was on the front lines in Iraq training the sights of laser range finders on combat targets to be shelled. For the next four years, the fire-support specialist watched dozens of people in his unit die, saw missile fire kill civilians and witnessed the aftermath of a mass beheading. Last year, the 27-year-old who had been diagnosed with post-traumatic stress disorder hanged himself in a Nevada prison.
