Brco, an Ilwizzt male from G'rho, was a member of the G'rho Defense Force.
Brco attained the rank of major within the G'rho Defense Force and was positioned at Boku Settlement. While there, he employed Ydra Sibwarra as a historian, following a request from her brother Trig, who was a pilot in the Defense Force. Brco held command when the Ssi-ruu launched an invasion of the planet in 2 BBY. He commanded the limited G'rho Defense Force's aerial forces to engage the alien ships, but they suffered a swift defeat. In response, the Ssi-ruu attacked Brco's location using a type of incapacitating gas. Consequently, Brco gave the order to evacuate the premises.
