|Notes||After developing a new carriage in which to mount their M1918 howitzers, the army decided to design a new howitzer instead of utilizing the older model, resulting in the M1 howitzer mounted on the M1 carriage. This same carriage was also used to mount the 4.5in gun which was to partner the new howitzer. The M1 had a longer barrel than the M1918 and had a new improved breech. The howitzer M1 was to replace the vintage M1918A3 which were still in stock, the M1 proved to be the best medium howitzer available to US forces not only in WW2 but in Korea and Vietnam. Along with the M2A1 105mm, formed the back bone of US Artillery Regiments.|
