Alpha-23, also known as Vuun was an ARC Trooper who served in the Clone Wars. He led an elite squad made up of other ARC Troopers. Vuun was activated early in the Clone Wars at the Battle of Kamino. He ended up serving in several campaigns during the Clone Wars, earning several honors, including Jaig Eyes. At the end of the Clone Wars, Vuun's squad received Order 66. Vuun pulled himself and his friend, Jedi Knight, Vorin Murc, off a ledge. Not realizing what Vuun intended, his squad labeled him as missing in action. Vuun survived, and retired and lived a quiet life.
