I'm thinking of the Lensmen series--the stardrive ejects non-interacting particles and thus doesn't tear things up. And since it's inertialess you can't use it to accelerate an impactor. However, you can go grab something that's already moving how you want, slap an inertialess drive on it and reposition it so that when the drive is turned off it's heading for your target. When it's a planet you fling around that can be pretty dangerous. And when it's a FTL planet (everything is Newtonian, this doesn't cause issues other than for the crew--can't allow one atom of native matter into your ship, can't use one atom from your ship in the drive on the planet) the results are spectacular.
(Note that they also have normal reaction drives in the Lensmen universe--the stardrive will get you to your objective but you still need to match velocities with it. And that does tear things up and we see it's use as a weapon, although not against a peer-class opponent.)
