The base has not released the identity of the soldier killed in the crash since it is Army policy to wait 24 hours after family members are notified, Kim Reischling, a spokeswoman for Fort Polk, told Military.com.
The soldiers in the Black Hawk were assigned to 1st Battalion, 5th Aviation Regiment, at Polk and were responding to a call for medevac from inside the training area at the Joint Readiness Training Center (JRTC) at approximately 12:15 a.m., Reischling said.
"This was a Fort Polk unit, and they were flying a real-world medevac mission to pick up a minor injury out there in the box. And that is when the mishap occurred," she said.
Reischling described the three soldiers' injuries as "minor to stable."
One soldier was taken to Bayne-Jones Army Community Hospital, and the other two were taken to Rapides Regional Hospital in Alexandria, Louisiana, she said.
The U.S. Army Safety Center at Fort Rucker, Alabama, will investigate the crash, Reischling said.
Fort Polk trains between 4,000 to 5,000 soldiers a year at JRTC, she added.
