The Air Strike Force (ASF) was an aerial military subdivision of the General Resource Defense Force, formed around the early 2030s. During GR's political expansion, the ASF was formed to deal with any perceived threats to its advance. In 2032, a group called the United Air Defense arose to stand against General Resource's expanding corporatocracy. The UAD went on a series of attacks against ASF bases across the Usean Continent, slowly beating back the General Resource forces. Eventually, the Air Strike Force decided to wipe out the United Air Defense once and for all with a cruise missile strike from their final stronghold. The base was destroyed, and the ASF is presumed to have been dissolved after the UAD incident.
