Bronco was a mercenary pilot belonging to the Bone Arrow Squadron. He wasn't well-known, and mostly kept to himself. Most of his contribution to the squadron occurred during Operation Crusher, in which he assisted the rest of the squadron in destroying the Stonehenge Type-3 railguns.
Bronco has a reputation among the Ace Combat community for being an extremely silent wingman, a first for the series where wingmen are usually the only characters talking. His only spoken lines are during Stonehenge, Avalon and Operation Bunker Shot.
