War was the leading cause of death in the military nearly every year between 2004 and 2011 until suicides became the top means of dying for troops in 2012 and 2013, according to a bar chart published this week in a monthly Pentagon medical statistical analysis journal.
For those last two years, suicide outranked war, cancer, heart disease, homicide, transportation accidents and other causes as the leading killer, accounting for about three in 10 military deaths each of those two years.
Transportation accidents, by a small margin, was the leading cause of military deaths in 2008, slightly more than combat.
