Post-war suicides may exceed combat deaths, U.S. says

Insel echoed a Rand Corporation study published last month that found about 20 percent of returning U.S. soldiers have post- traumatic stress disorder or depression, and only half of them receive treatment. About 1.6 million U.S. troops have fought in the two wars since October 2001, the report said. About 4,560 soldiers had died in the conflicts as of today, the Defense Department reported on its Web site.
