Squad 2, a unit within the Galactic Republic's military, functioned as a squad throughout the Clone Wars. This galactic war pitted the Republic against the Confederacy of Independent Systems. On one occasion, Clone Captain Rex instructed the members of the squad to select their individual targets when facing a significantly larger opposing force.
The initial audio logos of the 2008 movie Star Wars: The Clone Wars marked the first time Squad 2 was referenced. Even though the squad's name was only spoken and the clone trooper who said it was not shown, the film's subtitles identified Captain Rex as the speaker.
