|Notes||Designed as a light Howitzer mainly for airborne use, the M3 was a combination of a shortened 105mm barrel mounted on a modified 75mm M3A3 carriage which had split trails. It fired a faster burning round then the field version and had a short range. The M3 was also the standard field piece issued to Infantry cannon companies and were usually held at regimental level. The M3 partnered the lighter 75mm M8 Howitzer in Airborne and Marine Field Artillery Regiments.|
