With all the Demolishers flying around lately (some quite literally ;)), I thought I'd revisit an old take of my own on the concept, though I couldn't then resist the temptation to spruce it up a bit. The engine and armor stayed the same, the more up-to-date autocannons and AMSs are new additions:

If the turret armor seems a bit heavy, that's actually a legacy of the original Demolisher's 40/30/20/40 armor layout. And while I'm not sure the rules were around yet at the time, going that route actually does make a degree of sense if you ever get the chance to go hull-down in suitable terrain as per TacOps...
