Senior Master Sgt. Edward Mueller, 28th Logistics Readiness Squadron superintendent of fuels management, falls into a dunk tank during the annual base picnic outside the Dakota’s Club on Ellsworth Air Force Base, S.D., June 22, 2018. The dunk tank event was part of the Air Force Ball Dunk-a-Leader fundraiser, which involved nominating base leadership to be dunked in a tank of water, and the money raised from the event will go toward the base’s 2018 Air Force Ball in September.
