Smart Gunner PFC Vasquez was recruited from juvenile prison, where she had been serving a life sentence. Upon joining the US Colonial Marine Corps, she is trained in the use of the M56 Smart Gun. When ordered to use only flamethrowers in the Atmosphere Processing Station, she reluctantly hands over her ammunition and then loads a spare clip when Sgt. Apone's back is turned. She hands another to PFC Drake. When the aliens attack, she and Drake open fire, covering the Marines' retreat.
