Warmachine: Cygnar - Hammersmith

A slow Warjack that goes into overdrive once it gets into melee if it activates its Chain Attack successfully. While it doesn't win any awards for its P+S, if you can successfully Smite a model and Follow Up, any further focus can be used to generally wreck your target.

Combine that with Beat Back and you have a high ARM model that can end up in a very inconvenient place for your opponent at a low cost.
