'Three of our best': US Army identifies soldiers killed in Alaska helicopter crash

Military officials have identified three soldiers killed last week after two Army helicopters collided near Healy, Alaska, according to a statement from the U.S. Army's 11th Airborne Division.

The helicopters were returning to Fort Wainwright from an aerial gunnery range southeast of Fairbanks when they collided, officials reported.

Those killed in the crash were identified as Chief Warrant Officer 3 Christopher Robert Eramo, 39, of Oneonta, New York; Chief Warrant Officer 2 Kyle D. McKenna, 28, of Colorado Springs, Colorado; and Warrant Officer 1 Stewart Duane Wayment, 32, of North Logan, Utah.

John Pennell, a spokesperson for the U.S. Army Alaska, said a fourth soldier survived and remained hospitalized Sunday. He was not identified by military personnel.

"The battalion is devastated and mourning the loss of three of our best," Lt. Col. Matthew C. Carlsen, the 1-25th AB commander, released in a statement. "Our loss, however, cannot be compared to the suffering and loss which the family members ... are experiencing."

Army grounds aviation units for training after 12 soldier deaths

The deadly helicopter crash in Alaska came a month after nine soldiers were killed in a helicopter crash during a nighttime training exercise near Fort Campbell, Kentucky.

The fatal incidents prompted the Army to ground aviation units for training, according to Lt. Col. Terence Kelley, an Army spokesperson. The suspension of air operations was effective immediately, with units grounded until they complete the training.

For active-duty units, the training is to take place between May 1 and 5. Army National Guard and Reserve units will have until May 31 to complete the training.

"The move grounds all Army aviators, except those participating in critical missions, until they complete the required training," the Army said in a statement.
