| Notes | The M20 was an enlarged version of the M18, the 75mm round gave the weapon more punch, but unlike the M18 it could not be fired from the shoulder. It could be mounted on a tri-pod or on a light vehicle or jeep. It fired HEAT, HE and WP rounds. It saw limited action in World War Two but made its mark during the Korean War. |
