U.S. Forces Suicide Deaths Spike: There have been about 50 percent more suicides among U.S. troops this year than soldiers killed in action in Afghanistan, the AP reports, citing Pentagon statistics. In the first 155 days of 2012, there have been 154 suicides — note that it's nearly one per day.

Suicides had not risen in 2010 or 2011 and officials are surprised by the rise, AP says, although incidents of sexual assault, substance abuse and domestic violence are an increasing problem.

Why are suicides rising? The Pentagon isn't sure, but AP notes studies that have called out PTSD, prescription drug abuse, money troubles and multiple combat tours as possible causes for more suicides among troops. But how to account for the fact that many of the Army's suicides are by soldiers who have never seen action? via AP
