The Air Armaments Service (航空武装隊 Kōkū Busō Tai, official abbreviation AAS) is the aerial branch of the TSAB armed forces managed by the Main Office. While its membership is not restricted to aerial mages (such as support members like helicopter pilots), the AAS is considered one of the more challenging and demanding branches of service and the requirements are very high. Teana Lanster failed her entrance examination on her first attempt.
