Delta Squad was an elite clone commando squad that carried out demanding missions for the Grand Army of the Republic during the Clone Wars. Comprised of four clones of the Mandalorian bounty hunter, Jango Fett, Delta Squad included RC-1994, RC-2419, RC-5179, and RC-0419—informally known as "Boss", "Fixer", "Sev", and "Scorch", respectively. During the Clone Wars, Delta Squad went on a lot of very hard missions.
