This specific platoon fought for the Galactic Republic's 501st Legion throughout the Clone Wars, reporting to Jedi Generals Obi-Wan Kenobi and Anakin Skywalker, along with Clone Captain Rex, who held command. During the One-Day War, Rex and his fellow clones in the platoon were equipped with cold-assault gear, functioning as clone cold assault troopers. Similar to other platoons within the Grand Army of the Republic, this one consisted of four squads, with First squad being one of them. They made use of LAAT/is, BARC speeders, and CK-6 swoop bikes for transportation and combat.
The first appearance of the platoon occurred in the animated TV show Star Wars: The Clone Wars during the "Trespass" episode, the fifteenth of first season, although it wasn't identified by name at that time.
