Staff Sgt. Trevor Goss, left, and Airman 1st Class Chad Erwin, 480th Expeditionary Fighter Squadron munitions section, deployed from Spangdahlem Air Base, Germany, employ a rim gauge to check 20mm rounds used in the F-16 Fighting Falcon during a Flying Training Deployment at Monte Real Air Base, Portugal, Feb. 4, 2020. This procedure ensures the rounds can move seamlessly through the aircraft’s cannon without jamming. During this pre-planned training engagement, F-16s from the 480th EFS are participating in training focused on maintaining joint readiness while building interoperability capabilities with NATO and other U.S. Air Force assets.
