Ellsworth Honor Guard trainees learn how to perform a firing party drill during training in the Pride Hangar at Ellsworth Air Force Base, S.D. Sept. 19, 2013. The firing party ceremonial tradition dates back to the Civil War, and consists of three volleys fired to symbolize the removal of deceased bodies from the battlefield.
