Just wanted to point out these 2 gems from the new Lathe Worlds book from the DH range to fellow OW (beta) GM's in case you missed them: the Rapier Laser Destroyer and the Tarrantula weapons platform. Perfect additions to an OW game!
Both of them are self-mobile weapon platforms controled via a remote control box. The rapier is armed with a suped up las-cannon (enough to do more than 20 SI to a Leman Rus from the front in one hit on average) while the tarantula is more of a sentry-gun armed with twin linked heavy weapons.
And no, I won't post stats… that would be naughty!
