YouTube user rhauf1 shares with us this vehicular concoction dubbed Chainlink, assembled from salvaged and custom parts. The engine is a fuel-injected Ford 5.0 V-8 from a Cobra, and transmission and t-case from an old Bronco, but the real treat is the hydraulically-controlled swing arms.
Now, put some tractor treads on the arms and encase the mechanism in blast proof housings. Fit it with laser cannons and a rail gun.
