Another variant on Forpost's Zerber Chassis (it and the hull gun in the thumbnail are not included here) - Sometimes you really need just one very large missile to make that thing Over There decide to Go Away. Kitbashed from several similar vehicles. I can't claim much original partcrafting beyond some rescaling here and there.

Also includes parts from Vontragg's missile launcher and Solutionlesn's Scourge superheavy tank over on a certain Cultish website.
