Upon his promotion to Commodore, he and his staff began to develop special equipment and tactics for use by Navy personnel in situations similar to those which he had encountered while commanding the Wayrunner. When Tobonne was promoted to Rear Admiral in 5,006 BBY, he began advocating for the formation of a Marine Corps, an autonomous service branch that would fill the gap between the Navy and the Republic Army. As he envisioned it, the Corps would use the tactics that Tobonne had developed during his years of pirate-hunting on the Rim. His vision, enacted at the height of the Great Hyperspace War, would help to preserve and protect the Republic from then until the adoption of the Ruusan Reformation.
