-- Staff Sgt. David Countie helps form a security perimeter around the trucks of the Red Tail Express recently. The express delivers supplies to servicemembers at forward-deployed locations. When the vehicles stop, people riding shotgun set up the perimeter to deter aggressors while the drivers check their cargo. Countie is assigned to the 332nd Vehicle Operations Squadron.
