Broca Beach is Cobra's secret base on the east coast of the United States. It is a small town that has been completely overtaken by Cobra – every man, woman, and child in the city is related to Cobra in some way, as a direct agent, a member of Cobra Youth, or at least a member of a Cobra-supportive household. The town appears completely normal on the surface, but hides a fully-functional Cobra base below. G.I. Joe is currently unaware of its existence.
