C-deck was a location in the Undercity of Sundari on Mandalore. During the Siege of Mandalore, a ground unit of the 332nd Company were dispatched to reinforce C-deck, but were ambushed by the renegade Sith Lord Maul, sustaining heavy casualties. After the attack, former Padawan Ahsoka Tano and Clone Commander Rex visited the spot of the ambush, and after learning what had happened, Tano ordered Rex to make sure C-deck was properly fortified.
