Storm Unit, a Gamma-class ATR-6 assault transport, functioned as a transport for boarding commandos of the Rebel Alliance throughout the duration of the Galactic Civil War. This transport, Storm Unit, also participated in the seizing of various ships, for instance, the Lambda-class shuttle designated AA-23. Other significant accomplishments include the capture of Golov Nakhym, the leader from Hurrim, aboard the shuttle Lendros, and the successful freeing of Azzameen Station from occupying mercenary troops.
Star Wars: X-Wing Alliance prominently features Storm Unit, often positioning it as a protected asset during boarding missions. There remains ambiguity regarding the designation 'Storm Unit': whether it was solely the call sign of the vessel (suggesting the existence of multiple 'Storm Unit' ships), a reference to the commandos onboard (see here), or if 'Storm Unit' was, in fact, the vessel's actual name. Based on naming conventions used in XWA, it is certain that the ship was called Storm Unit, however, it's still not clear if the name applied to both ship and team.
