| Notes | Based on the M3 chassis and built by White. The T-30 was stop-gap design to provide the US Army with self-propelled howitzer, it served in reconnaissance platoons attached to armoured Infantry regiments as a support weapon. The vehicle was gradually phased out by mid-1943 and replaced by the M8 HMC. The T30 saw action in North Africa, Sicily and Italy. |
