The UNSC Vanguard is a large anti-armor assault bot used in both offensive and defensive situations. Armed with a pair of deadly Gauss Cannons, the Vanguard can efficiently take down enemy vehicles. The three legs allow it to maneuver over rugged terrain easier, as well as provide stability when firing its weapons. Attached to the back of each leg is a claw that dig into the ground and lock the Vanguard in place.
