M1917 Howitzer Carriage, Model of 1917 Schneider

155 mm Howitzer Carriage, Model of 1917 (Schneider) was the official name of this howitzer in US Army Service.

The US Army purchased over 1,500 of these and used them in both World War One and World War Two.

In the 1930s the US Army  began to modernize these with rubber tires, because wooden wheels are only suitable for towing by horses.  When towed too quickly wooden wheels will bounce and flip the gun, and maybe the towing vehicle.

The US Marines also used this weapon in the Pacific in World War Two.

These howitzers were organized into batteries of four.

And in companies of 12.  In the Interwar period they were often assigned to Infantry Divisions to make up for the lack of a 105mm gun.  Due to budget restrictions there was no money for 105mm artillery procurement.
