R2-M5 is an R2-series astromech droid from the Star Wars universe, known for serving aboard a Republic cruiser during the Clone Wars era. Like other astromechs, it is built for ship maintenance, navigation support, and technical assistance in combat situations. R2-M5 appears in the animated series Star Wars: The Clone Wars, where it functions as a background support droid rather than a major character. Its role reflects the everyday machinery that helps keep starships and crews operational in the larger galactic conflict.
