Scorpion Island is a military complex within the Skully Islands.
Some time after the start of the Skully Islands insurrection, rebel forces took over Scorpion Island and used it as one of their main bases.
As the FCU forces pushed back and regained territory, they eventually targeted Scorpion Island as one of the main points in the rebels' vital infrastructure. Seeing as the base itself was virtually impenetrable through normal attacks, they decided that the most favorable course of operation would be to isolate Scorpion Island from the mainland. Thus, the allied forces dispatched the mercenary Scarface Squadron to destroy the island's main links to the country. During their assault, they destroyed the island's suspension bridge and razed its air base, severing the base's links to the rest of the island chain.
