New study links pre-existing risks to rise in Army suicides

Roughly 18 out of every 1,000 Army soldiers commit suicide every year, while many more attempt or consider killing themselves. A new study on the rise in suicides found that 1 in 10 soldiers could be diagnosed for an anger impulse control disorder. Jeffrey Brown talked to Dr. Ronald Kessler of Harvard Medical School about how pre-existing mental illness may make soldiers more vulnerable.
