Close Quarters

Close Quarters - Victor Milán, Victor Milán Cassie Stuthorn is a foot-slogging Scout for Camacho's Caballeros mercenary regiment. Because she's the main character in this book, there isn't a lot of mech action, concentrating on what made her what she is.
Her backstory is a bit trite, and has been done before, but the supporting characters help raise the story.

There's a lot of intrigue going on as the Caballero's go to work in Draconis space, with the secret police and yakuza attempting to get to their employer.

When the mech battle does get going then it's worth the wait.
