I am searching for a book (probably early 2000s) which contains a specific scene. I do not remember everything and the details might be somewhat different, however, this is the gist:
The story plays at least a couple of hundred years in the future, in a technologically advanced society (spaceships, force fields).
A group of people try to [steal something/break something/???] in a heavily secured [facility/spaceship shipyard]. To achieve this, they first steal an "ancient" (by their standards) [tank/mech/piece of technology] (from a museum?). This [tank/mech/piece of technology] has a specific trait, namely, it can dig well - so they use it to dig under the [force field/shield] that surrounds the facility, but only reaches X meters below the surface. Of course something goes wrong with their plan, but I don't remember what, and how they worked around it (if they did).
IIRC, this should be somewhere on the axis between soft and hard sci-fi, so its not some kind of Star Wars wonderland.
