G.I. Joe learned the base's location when hunting for Mara, who had been taken prisoner by Cobra. In October of 2008 the Joes staged a covert infiltration of the base, as well as a smash-and-grab rescue when the infiltrators were discovered. In February of 2009 Cobra lured the Joes into staging a full-scale invasion of the base. Once the Joes were in place, Cobra pulled out and destroyed the base, killing most of the Joes' support force.
