Staff Sgt. Courtney Corral and Staff Sgt. Gerald Kelley, 11th Security Support Squadron run with an explosive ordinance disposal training device during the inaugural Battle of the Badges at Joint Base Andrews, Md., Oct. 21, 2016. Teams of four ran a half-mile with two people carrying the EOD training device while the other two teammates ran behind them; the teams were allowed to switch the device between members but could not allow it to drop below their knees.
