The squad was comprised of numerous clone stormtroopers and led by Clone Marshal Commander Cody. The squad also included team two, and utilized a Nu-class attack/transport shuttle flown by clone trooper pilots. The clone troopers were equipped with standard Phase II clone trooper armor, and used DC-15A blaster carbines along with a few BT X-42 heavy flame projectors. One clone commando, Crosshair, was also a member of the squad.
At the conclusion of the Clone Wars and the rise of the Galactic Empire in 19 BBY, a Confederacy of Independent Systems stronghold on the planet Desix refused Imperial authority and kidnapped their assigned governor, Governor Grotton, and held hostage. As a result, Vice Admiral Edmon Rampart assigned clone commando Crosshair to a squad led by Clone Commander Cody to rescue the governor and established Imperial control.
Grotton is held hostage by Ames.
The squad was transported to the planet in a Nu-class attack/transport shuttle, but as they approached the main city were met with missile fire, resulting in several hits. The shuttle crashed unto the surface near the city's outer perimeter, with several troopers killed in the crash. After eliminating a unit of battle droids sent to check for survivors, Cody, Crosshair, and the contingent of clone survivors moved in and attacked the stronghold. After sustaining several casualties destroying an Armored Assault Tank Mk I and a number of droids, the squad moved in to the main stronghold. The squad split up, with team two tasked with other objectives while Cody, Crosshair, Nova, and Wyler moved in to liberate Governor Grotton. After losing Nova to Commando Droids and Wyler to a Droideka, Cody and Crosshair moved in to Grotton's position, eliminating scores of droids. Once the Separatist holdout's leader, Governor Tawni Ames was persuaded to peacefully surrender, she was executed by Crosshair on the orders of Governor Grotton. Team two finished off any surviving droid forces, and members of the squad were extracted off-world by the same Nu-class shuttle that Grotton previously arrived on as Imperial forces of TK troopers arrived to occupy the planet.
Unsure if the Empire was in the right, Cody abandoned the Imperial Military after the mission. Rampart, who had never bothered to learn Cody's name in the first place and only knew him as CC-2224, assigned Crosshair a new mission under clone trooper officer CC-1226.
