Most of the trucks used by the French Army for transporting equipment and personal were of civilian design. The only modifications performed on these vehicles to make them serviceable for the military was the addition of tow hooks to aid in the recovery of the vehicle.
The French Army made a use of a number of 6x6 tractors, including the Laffly W15T. The Laffly W15T was a low-profile version of the Laffly S15T and featured the same bumper wheels that helped prevent the vehicle from bogging down when crossing trenches or rough terrain. The Laffly W15T was a prime gun mover in the French Army and was commonly used to pull the 47mm SA-37 anti-tank gun into battle.
