They died Sunday, August 13 of wounds sustained while engaged in combat operations in Iraq, a DOD news release stated.

Both soldiers were canon crew members assigned to 2nd Battalion, 319th Airborne Field Artillery Regiment, 2nd Brigade Combat Team, 82nd Airborne Division, Fort Bragg, North Carolina.

A Pentagon spokesman says the two U.S. soldiers were casualties of a U.S. artillery “mishap.”

The Pentagon spokesman, Army Col. Rob Manning, says an Army artillery unit was firing on an Islamic State mortar position “when a mishap occurred.”
Manning says there is no indication that IS played a role in the deaths. He says he cannot provide other details because the incident is under investigation.

Allen Stigler Sr., the Arlington soldier’s father told CBS11 Monday night,  “I want to know. Was my son conscious, when this happened, when this explosion happened. Did he say get my pops on the phone. What ever, at that time. I just want to know what happened.”

This was Stigler’s first deployment. He was scheduled to come home in October. He graduated from Timberview High School in 2013.

Five others suffered injuries that Manning says are not life-threatening.
