PETERSON AIR FORCE BASE, Colo. — Members of the 3rd Combat Communications Group, Tinker Air Force Base, Okla., celebrate being awarded the Etchberger Trophy for Best Combat Communications Team during the Guardian Challenge 2010 awards dinner May 21. Every two years, Air Force Space Command hosts Guardian Challenge, the premier space and cyberspace competition in the world. Teams from nine wings and one center, including newly added Air National Guard units, were part of GC 2010 competition events. Unlike GCs of the past, 2010’s competition included cyberspace forces for the first time. (U.S. Air Force photo by Duncan Wood)
