About 50 Alaska Army National Guard members will deploy to Guantanamo Bay, Cuba.
The guardsmen from the 761 Military Police Battalion, 38th Troop Command, will serve about a year.
The soldiers will join up with about 30 members of a subordinate unit who deployed in September for training in Texas ahead of the Guantanamo Bay assignment.
The guardsmen will care for detainees and conduct intelligence collection, analysis and dissemination.
