ANCHORAGE -

About 20 Alaska Air National Guard members are scheduled to deploy Tuesday to the Horn of Africa as part of Operation Enduring Freedom.

The soldiers are members of the guard's high-risk rescue crew, the 212th Rescue Squadron, or the 176th Operations Group. The guard says in a release that part of the mission is to support partner nation operations in East Africa to defeat extremist organizations.

They will replace about 25 Alaska Guard members who have been conducting missions in Africa since May.

This deployment is for about three months, and guardsmen should be back by early October.
