Anthony Terry, 446th Force Support Squadron (FSS) fitness noncommissioned officer in charge, instructs FSS Reserve Citizen Airmen on how to operate an airtronic burner during the Single Pallet Expeditionary Kitchen (SPEK) training exercise on Joint Base Lewis-McChord, Washington, Aug. 13, 2020. The SPEK, a tent-based field kitchen, provides 550 Airmen with three hot daily meals. Powered by its own diesel generator, the SPEK requires no external utility support and can be set up in nearly any climate. (U.S. Air Force photo by Staff Sgt. Mary A. Andom)
