| Notes | By 1943 the M31 tank recovery vehicle were gradually phased out and replaced by a new design based on the M4 medium tank. The new vehicle was called the M32 and featured a fixed turret with a dummy gun. Instead of a crane the M32 had an A-Frame which could be swung forward for heavy lifting or be left down for towing other vehicles, it could lift up to 27.000 kg. A winch was also added to the hull front for direct pulling. It was armed with a .50 cal located on the turret roof and a bow mounted .30 cal. Some variants carried an 81mm mortar was mounted on the hull front and was used to fired smoke rounds. The M32 was also used in the Korean War. |
