Lt. Col. David Herndon, the 28th Security Forces Squadron commander, gives a high five to one of the children enrolled in the School Age Care program at Ellsworth Air Force Base, S.D., June 25, 2021. Ellsworth SAC program students participated in a field trip to the 28th SFS that included a tour of the squadron, a military working dog demonstration, climbing around various security vehicles and more. Tours allow defenders the opportunity to answer questions the community has about their mission of providing base defense and resource protection to all members who live and work on Ellsworth.
