The number of suicides among U.S. Army active duty and reserve personnel in 2012 is higher than the total combined military fatalities from Operation Enduring Freedom in Afghanistan over the same timeframe.
Even without Army data  for October, the number of deaths believed to be suicides among U.S. Army personnel from January through September still surpass the combined military combat deaths in Afghanistan from January up to October 22.
In 2012, there have been a total of 247 suspected suicides among Army active and reserve duty personnel. Of those, 158 have been confirmed as suicides and 89 remain under investigation.
According to the Afghanistan Index database  maintained by the Brookings Institution, there have been 222 combined military deaths in 2012 among active and reserve components from “hostile causes,” as of Sept. 28. (p. 11 Figure 1.17)
