Col. John Roscoe, 305th OG commander, speaks with Lt. Col. Jimmy Shaw, 305th Operations Group deputy commander, and Chief Master Sgt. Samuel D’urso, 305th OG superintendent, about the ‘Elephant Walk’ exercise shortly before it kicked off Dec. 20, 2011, at Joint Base McGuire-Dix-Lakehurst, N.J. An ‘Elephant Walk’ is a fundamental training element when preparing for Global Strike Missions. In all, the exercise involved 12 KC-10s as part of a global-strike package designed to demonstrate the capability of the Air Force to assemble a large refueling force.
