The Bone Arrow Squadron (骨矢印飛行隊 Hone Yajirushi Hikō-tai) was an mercenary fighter squadron in the early 21st century. The squadron was formed under Arrows Air Defense and Security, a private military organization that operated in the wake of the Ulysses Disaster. Following the creation of the USEA Federation, the United Nations Forces absorbed Arrows's private military units, including Bone Arrow Squadron, which would become one of the two main flights in Task Force 118.
