Two of the soldiers died at the scene and the third died while being transported to a hospital, according to a release from the US Army’s 11th Airborne Division.

The names of the deceased are being withheld until 24 hours after their families have been notified, the release said.

The crash occurred about 100 miles south of Fort Wainwright, where the helicopters are based as part of the 1st Attack Battalion, 25th Aviation Regiment.

“This is an incredible loss for these soldiers’ families, their fellow soldiers, and for the division,” Maj. Gen. Brian Eifler, commanding general of the 11th Airborne Division, said in the release. “Our hearts and prayers go out to their families, friends and loved ones, and we are making the full resources of the Army available to support them.”
