The 4.2" mortar motor carriage M2 was based on the scout car M3. The machine gun skate rail was removed from the rear compartment, and the mortar mount was emplaced centrally. The mortar could be detached from the vehicle for firing. An ammunition rack for the mortar was installed behind the 3-man driver's compartment, and two seats were retained in the rear for the gun crew. The rear seats needed to be removed to access the mortar ammunition. The machine gun was installed on a pedestal mount on the passenger running board behind the front fender.
