Unditching roller

A M3 Scout Car showing the wide unditching roller at the front

The unditching roller is a device fitted to the front of military vehicles, such as the M3 Scout Car ^[1] and the M3 half-track, for the purpose of preventing the vehicle from getting stuck in an obstacle, such as a ditch.

Upon entering a ditch, the roller prevents the front of the vehicle from digging into the opposite face of the ditch; instead, the roller acts as a wide wheel enabling the front to climb out of the ditch more easily.^{[ citation needed ]}
