Students at the 366th Training Squadron electrical systems apprentice course perform a crossarm change out at Sheppard Air Force Base, Texas, May 28, 2019. Changing out the crossarm is important as they get damaged due to weather or rot that can deform the bar. The poles will likely be used and trained on by multiple classes, and students are also in charge of maintaining and replacing poles that are too worn out.
