11th Civil Engineer Squadron equipment operators clear snow from the flight line at Joint Base Andrews, Md., Jan. 23, 2014. As colder temperatures surround the installation, team members remain on-call and ready to assemble within moments. Nights before forecasted flurries, personnel arrive to work hours before precipitation hits, standing ready to move as soon as the first flake falls.
