Eight KC-10 Extenders taxi out to the runway Dec. 20 here in preparation for an ‘Elephant Walk’ exercise. An ‘Elephant Walk’ is a fundamental training element when preparing for Global Strike Missions. This was the first ‘Elephant Walk’ in nearly five years, with the 305th Air Mobility Wing launching all 12 KC-10 Extenders on the ramp, one right after the other, in a 30-minute time period. Members of the 32nd and 2nd Air Refueling Squadrons, as well as members from the 514th Air Mobility Wing, participated in the Employment Defense and Global Engagement exercise.
