In August UC 0080, multiple units were dispatched by the assault carrier Spartan for a patrol mission near Antarctica. They were then ambushed by several MSM-07 Z'Gok piloted by Zeon remnants and suffered heavy losses. Several were crushed by sinking icebergs. In the manga, the GM Marine Types were later used to stop traffic from leaving the Rig.
