Tech Sgt. Nathan Wiley, 10th Missile Squadron facility

Tech Sgt. Nathan Wiley, 10th Missile Squadron facility manager, right, and Senior Airman Bryan Williams, 341st Force Support Squadron missile chef, run through a pre-operation checklist in preparation for a helicopter refuel at a missile alert facility May 11, 2017, at Malmstrom Air Force Base, Mont. Some of the items on the checklist require a second person, so the facility manager will get assistance from either the missile chef or an available security forces member.
