Knight Captain Colvin

Knight Captain Colvin is a Brotherhood of Steel member inside the Galaxy News Radio building. He is wearing Lyons' Pride Power Armor and is armed with a Laser Rifle. After completing the Following in His Footsteps quest he returns to the Citadel.

There is a slight competition with Knight Captain Dusk over who is the better shot.

Of all the Lyons Pride members, Colvin is the nicest to the player character upon first meeting them.

Background
A sniper in Lyons' Pride, Colvin is 40, friendly, and warm to everyone; he has priest-like tendencies. To him, combat is like worship, and he treats his rifle as a holy object and his targets as the unfortunate victims of his god's wrath. He says a prayer for the soul of each mutant he kills. He's extremely experienced, and completely unflappable: all according to god's will.

Behind the scenes
Knight Captain Colvin is most likely a reference to the character Private Daniel Jackson (played by Barry Pepper) in the movie Saving Private Ryan. Like Colvin, Jackson is an army marksman who says a prayer before taking each shot.

Appearances
Knight Captain Colvin appears only in Fallout 3. Interestingly, aside from his initial appearance outside GNR, he appears in no subsequent quests or side missions, even those involving other Pride members.
