An unditching roller is a device fitted to the front of military vehicles, such as the M3 Scout Car and the M3 half-track, for the purpose of preventing the vehicle from getting stuck in an obstacle, such as a ditch. The C4 based Citroën P17C Kégresse from 1931 also had such a roller.

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.
