The Mole is a medium-sized tunneling vehicle used for underground missions. Once arrived at the danger zone, it exits its pod and is transported to the drilling location by a trolley with caterpillar tracks. A lifting ramp then tips it into position to commence drilling.
An additional set of caterpillar tracks on either side of the vehicle allows it to return to the surface independently, for retrieval. It's equipped with a thermal-imaging system, inside the drill-bit, to locate buried individuals.

Pit of Peril
Virgil had been lowered into the pit where the Army vehicle Sidewinder lay trapped, to place explosive changes prescribed by Brains. Scott then used the Mole to tunnel down into the side of the pit, to bring his brother back to the surface.
City of Fire
After the Firefly cleared a path through the burning rubble, Scott and Virgil used the Mole to drill down to the underground passage-ways of the collapsed Thompson Tower building, to rescue the trapped Carter family.
