The actor who plays Vagabond, Francois Chau, is from Cambodia, and has been in a variety of movies, television shows, and even theatrical productions. Nothing big lately, unfortunately. Heh, he played Shredder in the 2nd Ninja turtle movie.
that would be Admiral Geoffrey Tolwyn. Unfortunately only someone who read Wing Commander novells can truly understand what Tolwyn did (and why he took such course of actions).
Paladin: Ah, well, we have one problem: There is no bomb. A year ago, Dr Severin, the man in charge of this project, was captured by the Kilrathi. We’ve tried putting the pieces together without him, but ended up with zip.
Eisen: And now we have to go and get him.
Paladin: Well, it beats waiting for the Kilrathi to parole him.
Yeah, after Tolwyn told him that Blair had defected to the Union of Border Worlds, when Paladin went to the christening ceremony for the T.C.S. Vesuvius
Still, at least he gave his life honorably, which allowed Sosa to escape with the vital data which revealed the conspiracy that Tolwyn and the Black Lance were cooking up.
The Intrepid got a detachment of marines when Dekker and his squad came onboard, and yes, Vagabond did have a past as a covert ops officer. Eisen said it himself before Blair, Vagabond, and Sosa left for the comm station.
Dekker arrived after the comm station mission when Vagabond dies. Dekker's shuttle arrives sometime during or just before Melek and the Kilrathi arrive.
