Staff Sgt. Anthony Zappardo, 421st Combat Training Squadron Fieldcraft Contingency Response (FC CR) contingency skills instructor, explains to his students what a defensive fighting position should look like at Home Station Training Lane-West, Feb. 9, 2021, at Joint Base McGuire-Dix-Lakehurst, New Jersey. The students attended FC CR from Little Rock Air Force Base, Arkansas, to share their lessons learned with their units so they can provide feedback to the U.S. Air Force Expeditionary Center for the upcoming Mutli-Capable Airman course.
