365th Training Squadron electronic warfare apprentice course students go over an inventory checklist before they start work at Sheppard Air Force Base, Texas, Dec. 12, 2018. The students are checking each tool for an engraving to make sure they are the same tools as on the list. If an Airman who has lost a tool or noticed one has been missing, there will be more severe consequences though if it is not reported right away.
