Tech. Sgt. Renee Kiger checks in and issues tickets to passengers at Ramstein Air Base's passenger terminal, July 13, 2017. As a passenger terminal specialist and Air Transportation Journeyman with Joint Base Charleston's 81st Aerial Port Squadron, Kiger helped train at Ramstein with the active duty 721st APS. Because Ramstein's Aerial Port is configured differently - and is much larger - than JB Charleston's, it serves as an opportunity for real-world training for the 81st APS's Citizen Airmen.
