Despite beefing up its psychiatric staff, Fort Hood in Killeen, Texas, can't seem to stop a rising tide of soldier suicides, including a record 22 in 2010, over twice as many as the previous year. That's a rate of 47 per 100,000 people, well over twice the national average. Preparing to help soldiers through the trauma of a shooting on base that left 13 of their comrades dead, Fort Hood made its psychiatric staff the largest in the army, with 170 members. But the suicide number just keeps climbing. "We are at a loss to explain the high numbers," the base's acting commander said. "It's personally frustrating."
