Medical records show that when Tyler Jennings returned from Iraq last year, he was severely depressed and used drugs to cope. When the sergeants who ran his platoon found out, they started to haze him. He came close to hanging himself after officials said they would kick him out of the Army.

Corey Davis was a machine gunner in Iraq. He says he began "freaking out" after he returned to Ft. Carson; he had constant nightmares and began using drugs. When he sought help at the base hospital one day, he says he was told he'd have to wait more than a month to be seen. Courtesy Corey Davis

Jason Harvey was diagnosed with PTSD. In May, he slashed his wrists and arms in a cry for help. Officials at Ft. Carson expelled Harvey from the Army a few months ago for "patterns of misconduct." Harvey had been diagnosed with post-traumatic stress disorder.
