(pilot could you please just tell use what the name of the action novel is and the author? It would be so helpful for us to answer your question as to whether or not we agree with you that the words are inappropriate)
The only way I could see them being appropriate is if the author were trying to create a sardonic, smug narrator. Or if the language were self-mocking in some way, or intentionally antiquated. (Nelson DeMille is an author who does this a little -- but his MC admits to loathing pretentiousness.)
Otherwise, you're best to leave that kind of stuff out or else your readership's going to shrink to the size of a niche.
