The 42nd Assault Squad was an elite squad of clone troopers who served in the Clone Army during the final year of the Clone Wars. They were part of the 52nd Sky Corps under Commander CC-2079. They also pioneered the use of AT-RTs, BARC Speeders and Juggernauts, using them for reconnaissance and battles. They later joined the Clone Rebellion, questioned the goals of the Empire and deserted soon after.
