Security
SOUTHWEST ASIA (AFPN) -- Airman 1st Class Carin Brigham stands ready to ensure base perimeter security here. Airman 1st Class Erick Martinez backs her up with a M240 machine gun. Both Airmen are in the 379th Expeditionary Security Forces Squadron. The security forces career is undergoing a transformation that will affect the total force. These changes will present the opportunity for other Airmen to participate in installation security. (U.S. Air Force photo by Tech.Sgt. Sarah R. Webb)
