|Notes||The US army had initially laid plans for a 105mm howitzer back in the 1920s, this was after noting the performance of the different 105s used by European nations in World War One. The Army requested a divisional howitzer that could be towed by mechanized units and fire a 105mm shell. The choice of carriage was based on a German model that had a split trail. The development of the fixed 105mm round and a muzzle break to absorb the recoil were added but progress was slow. By 1939 the army had tested a new carriage and the M2 was standardized in 1940, this went into full production and went on to replace the 75mm guns in each of the three field battalions contained in each Infantry division. Later modifications to the breech ring developed into the new M2A1 which became the standard light regimental howitzer and saw action on all fronts.|
