Brco achieved the rank of major with the G'rho Defense Force, and was stationed at Boku Settlement. There he hired Ydra Sibwarra as a historian, at the bidding of her brother Trig, a pilot in the Defense Force. When the Ssi-ruu invaded the planet in 2 BBY, Brco was in charge. He ordered the small G'rho Defense Force air force to attack the alien ships, but they were easily defeated. The Ssi-ruu retaliated by attacking Brco's compound with some form of knockout gas. Brco ordered an evacuation of the facility.
