WASHINGTON — Suicides across the military dropped by more than 15 percent last year, but new detailed data reveals an increase in the number of Army National Guard and Reserve soldiers who took their own lives.

The overall totals provided by the Army, Navy, Air Force and Marine Corps give some hope that prevention programs and increased efforts to identify troops at risk may be taking hold after several years of escalating suicides. But the increase among Army National Guard and Reserve members raises questions about whether those programs are getting to the citizen soldiers who may not have the same access to support networks and help that their active duty comrades receive.

Not only did the Army National Guard and Reserve suicides increase from 140 in 2012 to 152 last year, but the 2013 total exceeded the number of active duty soldiers who took their own lives, according to the Army. There were 151 active duty soldier suicides last year, compared with 185 in 2012, Army officials said.
