Nguyen was a member of Raynor's Raiders in the SceeVee Special Engineering Corps. He was also a member of the ChariCorps even during his service as a Raider.
Nguyen worked as a structural architect, before being recruited by Bill "Pearly" Bousquette for his SceeVee Corps. During their operation on Gurdlac, the Corps tripped a zerg trap, and were ambushed by a swarm of zerglings. Nguyen was killed in the ambush.
