WHITEMAN AIR FORCE BASE, Mo. U.S. Air Force Guards men, Staff Sgt. Darry Walker (left), and Master Sgt. Mike Leddy, both 217th Engineering Installation Squadron, Springfield, Illinois, separate colored stands of fiber optic cable to determine which stands need to be spliced Sept. 24, 2009. Air Force Guard members from both the 271st and the 241st have spent over two months at Whiteman AFB replacing copper transmission cable with more efficient fiber optic cable. The fiber optic cable will provide 50% more capability and expansion to utilize a greater number of networked products. (U.S. Air Force photo/ Senior Airman Kenny Holston)
