"...all-terrain vehicle..." is an error. It is limited to the road only.
A large Armoured Fighting Vehicle (AFV) with a cannon mount typical of old-era tank designs. The default layout includes the Rumble Cannon which has unlimited ammunition capacity. This vehicle is ideal for road based attacks against strong hostiles in the air when they are distracted by X-com air assaults. The power of the cannon can level buildings from misses if aimed towards low flying or road based enemies. Two other weapons are specific to this design, a missile launcher and a plasma cannon to further customise its role. Smaller weapon systems may be mounted but are not ideal since other vehicles are better suited due to the cost and limited availability of this tank.

As with all road based vehicles:
Road vehicles are not very useful because all roads are too weak. The vehicles are good, the roads aren't.
