PSICOM

Unreleased PSICOM is the name of an elite military force in Final Fantasy XIII that opposes Lightning and her group. They are heavily armed soldiers clad in full-armor that employ machine guns in battle. PSICOM forces are aided by monsters, giant robots, and Airships in their fight against the fal'Cie. Since they oppose Lightning, they are probably on the side of Cocoon and its Holy Government. It is mentioned that these soldiers are the best the "Sanctum" has, though it is unknown what that term means at this time.
