Jaime Velasco was a human sergeant aboard the UNSC Infinity.

When the Infinty was boarded by Covenant and Promethean forces during the Second Battle of Requiem, Fireteam Crimson boarded the ship too in an attempt to free the ship. Velasco and his team were tasked with defending the engine room but were overrun by enemy forces.[1]
