Some ARVs are operated in tandem with armoured bulldozers. ARVs generally can only tow an equivalent-class vehicle or one that is lighter in weight. As such, an APC chassis-based ARV can only tow and recover an APC, but not a much heavier tank. While most ARVs are made from or based on APC or tank chassis, more rarely, an ARV may be based on an artillery tractor chassis. Some ARVs have specialized equipment that enables them to operate on beaches or in shallow water.
