Commander Nigel Alexander is the C.O., of the Gunstar Sentinel.

A Colonial Fleet Officer from Caprica, Commander Alexander comes from high society and maintains a certain air of culture and dignity at all times. However, even with his mannerisms, he was a ferocious fighter and tactical genius in space combat. While other officers aspired to be Viper pilots and command Battlestars, he was happy as a Gunstar commander, preferring the speed and maneuverability of the smaller ship to the raw firepower of a Battlestar. A hero to the end, Commander Alexander ordered his ship into the path of a nuclear missile that would have destroyed the Battlestar Prometheus. He died with his ship and was posthumously honored with the Gold Cluster, the Colonial Defense Forces highest honor for valor.


Original Alexander first name was David. Season 1 Ep 2, pg 10.
