Rostu Squad was a squad of Clone Troopers which served in the Grand Army of the Republic during the Clone Wars against the Confederacy of Independent Systems. During the war they were part of a battalion which was deployed to Kaller to fight the Separatists there. The Republic was victorious, but shortly after the battle, the Clones received Order 66. Rostu Squad and the rest of the battalion attacked Jedi Master Depa Billaba and her Padawan, Caleb Dume, who were stationed with them. Depa was killed holding off the Clones while Celeb escaped, and Clone Captain Styles ordered the squad to aid him in hunting down the Padawan. Rostu and Styles chased Caleb into nearby woodland, but the Jedi escaped and went into hiding.
