Delta Squad was a clone commando squad that was dispatched to Devaron and recovered the bodies of a Jedi and his Padawan that had been killed there.

CC-5576-39 was a clone commando, a captain of an elite squad of clones, and reported missing in action during the Battle of Sarrish.

The Advanced Recon Recommando or "ARC trooper" was a highly specialized type of clone commando.

Behind the scenes
The concept of clone commandos was introduced within the Star Wars Expanded Universe novel The Cestus Deception and the characters were later heavily featured in the game Star Wars: Republic Commando and associated media, as well as a number of other Expanded Universe products. These titles, however, have been re-branded as Star Wars Legends and are no longer considered canon. Clone commandos were introduced into Star Wars canon through Star Wars: The Clone Wars, first seen with Delta Squad in "Witches of the Mist." "Missing in Action" featured CC-5576-39, specifically referred to as a "clone commando," but suffering from amnesia and working as a dishwasher.
