Valiant Shield preparation
Master Sgt. John Bell, a production superintendent with the 67th Aircraft Maintenance Unit, pumps a jet fuel starter on an F-15, which enables the aircraft to start, Sept. 8. The F-15 is one of 18 departing for Valiant Shield, a joint training exercise held in Guam. More than 600 Kadena members are deploying in support of this bi-annual operation.
