Aside from what has already been mentioned, I would add Robert Thurston's Jade Phoenix Trilogy. Probably my favorite books in the series, although I stopped reading Battletech years ago, so I have no idea about the more recent books.
If you get to the third book do yourself a favor, once Aidan gets to Tukayyid put on the soundtrack to Last of Mohicans. Trust me, it'll add to the experience.
