Two U.S. Army helicopters arrived in Unalaska last week, but their mission is unclear.
The CH-47 Chinooks have been sitting on the airport tarmac, and soldiers have been spotted moving about and inspecting them.
"They're there as part of a joint effort with the U.S. Air Force and — I think — the U.S. Coast Guard," said Lt. Colonel Martyn Crighton, a public affairs officer for U.S. Army Alaska. "But honestly, I don't have the details."
He said the unit is from Fort Wainwright, the Army post near Fairbanks.
