Star Wars X-Wing (2nd Ed): Guardians of the Republic Squadron Pack - Rules of Play says:

This pack gives you everything you need to begin building your Galactic Republic squadrons, including one Delta-7 Aethersprite miniature and two V-19 Torrent miniatures. The chosen interceptor of many Jedi, the Delta-7 allows them to use their Force-enhanced reflexes to the fullest. Behind them, clone pilots cover them from their V-19 Torrents with coordinated fire, tight formation flying, and salvos of missiles. In addition to the miniatures, this Squadron Pack gives you the chance to further explore the potential of the Force with several new Force upgrade cards. Meanwhile, a wealth of other upgrade cards—including reprints of many common neutral upgrade cards—provide a wealth of options for customizing your squadrons.
