Personal work. Some thoughts on creating something that can demolish buildings, provide passage into or through buildings, over or under debris, acts like a bulldozer, provide cover from top fire and from frontal fire can tilt and adjust for other angle cover, can create a blockade and fire from behind it's shield with his front armshileds. Serve as a ramp, and can act as "safe" debris by preserving a space underneath when buildings collapse on it, also blends in by having a primitive and "broken" shapes. Has big footprint/horizontal cover surface it serves as a walkable surfaces (a bridge) and has and can form ramps, strong stand, strong leverage for pushing/lifting/demolishing, lifting in a car jack fashion, etc..
