The following article concerns the military formation, rather than Exosquad as the TV series. An exosquad is a tactical formation comprising of eight or nine exoframes, or e-frames for short. They are organized into numbered groups called flights followed by a phonetic letter corresponding to the number (1 – A; 2 – B and so on). The Exosquad TV series centred on the exploits of Flight One: Able Squad, commanded by Lieutenant, later Commander JT Marsh. An Exofleet officer of Commander rank may command or issue mission orders to two or even three Exosquads, such as the ill fated DeSoto in the episode Fire Ship.
